The Chicken GTF2F1 (General Transcription Factor IIF, Polypeptide 1) ELISA immunoassay kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Chicken GTF2F1. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Chicken GTF2F1 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Chicken GTF2F1, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Chicken GTF2F1. You can calculate the concentration of Chicken GTF2F1 in the samples by comparing the OD of the samples to the standard curve.

Revising my first review
Material Type: Updated-Stainless Steel
All the items were in the box. The grinders are easy to use. The quality of the product is excellent. I had another one from another company a while ago but this one here I would buy again. The light is brighter than most. The grinders works very well. I am resubmitting this review from my previous one. I give this one 5 STARS PLUS

Works and is engineered exactly as I expected it to be. Unlike SO MANY OTHERS.
Color: 2-Speed Rechargeable Set with Charging Base
I've ordered about 4 different automatic shakers from different brands. They all have different problems, motor not strong enough, charging cable on the front of the charging base (in the way on a counter), hard to open refil covers, small containers not holding enough salt/pepper. FINALLY this one checks all the marks I've been looking for. Its weighty too since its made of stainless. Large refil container, easy to remove just a twist. Grind selector is a twist at th e base with a clear arrow showing size. Large press button at top so you can hold it in any rotation in your hand and not have to look for the button/switch to turn it on. No cover that needs to be flipped open and then closed to put back into the base. Contacts for charge are on the back side and not at the bottom where salt can corrode the contacts. The list can go on but you get the idea. Just buy this one and be done with it!

Nice product
Color: 2-Speed Rechargeable Set with Charging Base
Edit: Customer service actually did offer to replace it. Received the new set and it works fine. Nice set. Only gripe is I think that the motor could be a little stronger. Sounds like it’s struggling at times. Received a defective item reached out to customer support for Circle joy and they’re basically saying that it’s user error and not a defect in their product, even though I explained to them that the other one works fine. When adjusting the coarseness on one of the grinders, the grinder ends up loosening up, which ends up with you spilling the pepper corns everywhere. It’s a nice set if it worked right but for $40 I expect her device to be a little more polished.
