Product Specification
| Usage | Required experimental equipment: 1. Microplate reader (450nm) 2. High-precision pipettes and pipette tips: 0.5-10uL, 5-50uL, 20-200uL, 200-1000uL 3. 37°C incubator 4. Distilled or deionized water Sample preparation and requirements: Tissue homogenization: Rinse the tissue with pre-chilled PBS (0.01M, pH 7.4) to remove residual blood (lysed red blood cells in the homogenate will affect the measurement results). Weigh and mince the tissue. Add the minced tissue to the appropriate volume of PBS (generally a 1:9 weight-to-volume ratio, e.g., 1g of tissue sample to 9mL of PBS. The specific volume can be adjusted according to experimental needs and recorded. It is recommended to add protease inhibitors to the PBS) in a glass homogenizer and grind thoroughly on ice. To further lyse tissue cells, the homogenate can be sonicated or repeatedly frozen and thawed. Finally, centrifuge the homogenate at 5000×g for 5-10 minutes, and collect the supernatant for analysis. Cell Lysis Buffer: Adherent cells should be gently washed with pre-chilled PBS, then trypsinized and harvested by centrifugation at 1000×g for 5 minutes. Suspension cells can be harvested directly by centrifugation. Collected cells should be washed three times with pre-chilled PBS and resuspended in 150-200 μL of PBS per 1×10^6 cells (it is recommended to add protease inhibitors to the PBS; if the cell count is very low, reduce the PBS volume appropriately). Disrupt the cells by repeated freezing and thawing or sonication. Centrifuge the extract at 1500×g for 10 minutes at 2-8°C, and collect the supernatant for analysis. Other biological fluids: Centrifuge at 1000xg for 20 minutes, remove the supernatant, and test. Pre-test preparation: 1. Remove the test kit from the refrigerator 10 minutes in advance and equilibrate to room temperature. 2. Prepare the standard gradient working solution: Add 1 mL of universal diluent to the lyophilized standard, let it stand for 15 minutes to completely dissolve, then gently mix (concentration is 20 ng/mL). Then dilute to the following concentrations: 20 ng/mL, 10 ng/mL, 5 ng/mL, 2.5 ng/mL, 1.25 ng/mL, 0.625 ng/mL, 0.3125 ng/mL, and 0 ng/mL. Serial dilution method: Take 7 EP tubes and add 500 μL of universal diluent to each tube. Pipette 500 μL of the 20 ng/mL standard working solution into the first EP tube and mix thoroughly to make a 10 ng/mL standard working solution. Repeat this procedure for subsequent tubes. The last tube serves directly as a blank well; there is no need to aspirate the liquid from the penultimate tube. See the figure below for details. 3. Preparation of Biotinylated Antibody Working Solution: 15 minutes before use, centrifuge the concentrated biotinylated antibody at 1000×g for 1 minute. Dilute the 100× concentrated biotinylated antibody to a 1× working concentration using universal diluent (e.g., 10µL concentrate + 990µL universal diluent). Prepare immediately before use. 4. Prepare the enzyme conjugate working solution: 15 minutes before use, centrifuge the 100× concentrated enzyme conjugate at 1000×g for 1 minute. Dilute the 100× concentrated HRP enzyme conjugate to a 1× working concentration with universal diluent (e.g., 10 μL of concentrate + 990 μL of universal diluent). Prepare immediately. 5. Prepare the 1× wash solution: Dispense 10 mL of 20× wash solution into 190 mL of distilled water (concentrated wash solution removed from the refrigerator may crystallize; this is normal. Allow to stand at room temperature until the crystals have completely dissolved before preparing). Procedure: 1. Remove the desired strips from the aluminum foil bag after equilibration at room temperature for 10 minutes. Seal the remaining strips in a ziplock bag and return to 4°C. 2. Sample addition: Add 100 μL of sample or standard of varying concentrations to the corresponding wells. Add 100 μL of universal diluent to the blank wells. Cover with a film and incubate at 37°C for 60 minutes. (Recommendation: Dilute the sample to be tested at least 1-fold with universal diluent before adding it to the ELISA plate. This will reduce the impact of matrix effects on the test results. The sample concentration should be multiplied by the corresponding dilution factor when calculating the final sample concentration. It is recommended to run replicates for all test samples and standards.) 3. Add Biotinylated Antibody: Remove the ELISA plate and discard the liquid without washing. Add 100 μL of Biotinylated Antibody Working Solution directly to each well. Cover with a film and incubate at 37°C for 60 minutes. 4. Wash: Discard the liquid and add 300 μL of 1x Wash Solution to each well. Let stand for 1 minute, shake off the wash solution, and pat dry on absorbent paper. Repeat this process three times (a plate washer can also be used). 5. Add Enzyme Conjugate Working Solution: Add 100 μL of Enzyme Conjugate Working Solution to each well. Cover with a film and incubate at 37°C for 30 minutes. 6. Washing: Discard the liquid and wash the plate five times as in step 4. 7. Adding substrate: Add 90 μL of substrate (TMB) to each well, cover with a sealing film, and incubate at 37°C in the dark for 15 minutes. 8. Adding stop solution: Remove the ELISA plate and add 50 μL of stop solution directly to each well. Immediately measure the OD value of each well at a wavelength of 450 nm. Calculating experimental results: 1. Calculate the average OD value of the standard and sample replicates and subtract the OD value of the blank well as a correction factor. Plot the standard curve of the four-parameter logistic function on double-logarithmic graph paper, with concentration as the horizontal axis and OD value as the vertical axis. 2. If the sample OD value is higher than the upper limit of the standard curve, dilute the sample appropriately and retest. Multiply the sample concentration by the corresponding dilution factor. |

| Theory | This kit utilizes a double-antibody sandwich enzyme-linked immunosorbent assay (ELISA). Sample, standard, biotinylated detection antibody, and HRP conjugate are sequentially added to microwells pre-coated with a capture antibody against SAM and SH3 Domain Containing Protein 1 (SASH1). After incubation and washing, the sample is developed using the substrate TMB. TMB is converted to blue by HRP peroxidase and to yellow by acid. The intensity of the color is positively correlated with the amount of SAM and SH3 Domain Containing Protein 1 (SASH1) in the sample. The absorbance (OD) is measured at 450 nm using a microplate reader to calculate the sample concentration. | |||||||||||||||||||||||||||||||||

| Composition |
|
|||||||||||||||||||||||||||||||||
| Background | SAM and SH3 domain-containing protein 1, also known as SASH1, is a protein encoded by the SASH1 gene. This gene encodes a scaffolding protein involved in the TLR4 signaling pathway, which may stimulate cytokine production and endothelial cell migration in response to invading pathogens. The encoded protein has also been described as a potential tumor suppressor that may negatively regulate cancer cell proliferation, apoptosis, and invasion, and reduced expression of this gene has been observed in various cancers. Mutations in this gene may be associated with abnormal skin pigmentation in patients. | |||||||||||||||||||||||||||||||||
| General Notes | 1. Strictly adhere to the specified incubation time and temperature to ensure accurate results. All reagents must be at room temperature (20-25°C) before use. Refrigerate reagents immediately after use. 2. Improper plate washing may result in inaccurate results. Ensure that all liquid in the wells is aspirated thoroughly before adding substrate. Do not allow the wells to dry out during incubation. 3. Remove any residual liquid and fingerprints from the bottom of the plate, as this will affect the OD value. 4. The substrate developer solution should be colorless or very light in color. Do not use substrate solution that has turned blue. 5. Avoid cross-contamination of reagents and specimens to prevent erroneous results. 6. Avoid direct exposure to strong light during storage and incubation. 7. Do not expose any reagents to bleaching solvents or the strong fumes emitted by bleaching solvents. Any bleaching agent will destroy the biological activity of the reagents in the kit. 8. Do not use expired products, and do not mix components with different product numbers and batches. 9. Recombinant proteins from sources other than the kit may not be compatible with the antibodies in this kit and will not be recognized. 10. If there is a possibility of disease transmission, all samples should be managed properly and samples and testing devices should be handled according to prescribed procedures. |

Fantastic for gaming and productivity, but missing USB-C rechargeability
Color: Classic Black, Color: Classic Black
I recently purchased the Razer Orochi V2, and overall, it is an amazing mouse. The build quality is absolutely fantastic, and it feels premium. It fits perfectly in my palm, and the materials and clicks have a very pleasant tactile feel. I use it daily for both gaming and work, and it performs flawlessly in both scenarios. Compared to my Razer Pro Click, the Orochi V2 actually fits my hand much better. In fact, I now only use the Pro Click as a backup for when the Orochi's battery suddenly dies!
There is really only one downside for me: it runs on disposable batteries rather than having a built-in rechargeable one. On the plus side, it only needs a single battery to operate, and I love the clever design that allows you to use either a standard AA or a smaller AAA battery depending on your weight preference.
However, I would really love to see a future version of this exact mouse with a built-in battery and a standard USB Type-C charging port. If you don't mind swapping batteries occasionally, this is a near-perfect mouse. Highly recommended!

Amazing mouse even for big hands.
Color: White
So I have big hands and what any big hand gamer understands is that you either have to get a big ol heavy G502 size mouse or use a certain grip to hold all these mice for smaller handed people. I previously owned a Model O, G pro, and Model O wireless.
Having big hands my biggest peeve with all the other mice is that they’re ambidextrous mice so they are even harder to hold with fingertip/claw grips because the smooth, near flat, symmetrical sides. I only really make contact with the sides by pinching my fingers with them. I never make contact with the butt or base of the mouse with my grip. There’s where the Orochi changes things
The Orochi somehow is a smaller mouse than all of the above but fills out my hand and grip SO much better. The sides actually have slight grooves so I don’t slip off the sides of my mouse and the shorter but bigger hump in the middle makes me for once actually feel the mouse in my palm if I want. Overall the feel is amazing.
Battery life varies of course but I can barely tell there’s a battery in the thing even when flicking and the weight and balance of it feel so good.
Mobile gaming is the main reason I got this mouse. I like that the dongle stores inside the mouse, uses batteries so I don’t have to worry about keeping it charged or bringing around extra cables to charge it, and the Bluetooth is good for casual gaming but doesn’t do great with big flicks so the 2.4ghz connection is required for esports games.
Overall a great mouse and really awesome to game with and a little plus to it is that the shell comes off the back so satisfying, it’s hard to not fidget with it by taking it on and off haha. Well worth the money and I’d expect they’ll make a rechargeable one with all the success this mouse has accrued so far so if the swappable batteries don’t tickle your pickle, I’d just buy a sub $20 rechargeable battery station or just wait for a new rechargeable Orochi to come out.

Great quick mouse <3
Color: White
Very nice mouse though the scroll wheel is a little hard but it doesn’t skip around or behave oddly. instant set up and very comfy! I’m a girl with small hands so it fit perfectly! not too big or uncomfy, I can naturally grip it and the color is so perfect for my pastel blue and white setup! The click is a bit loud but not annoyingly loud, feels very sturdy despite it being so light, I’d say it’s a good price for a gaming mouse! (no connection issues either with Mac) I don’t have a mouse pad and it actually glides pretty good on my wooden desk.
