Description

Retinol Binding Protein 4 (RBP4) ELISAThe Retinol Binding Protein 4 (RBP4) ELISA is an enzyme immunoassay for the quantitative determination of Retinol Binding Protein 4 (RBP4) in human serum and plasma. The microtiter plate is coated with the antibody specifically binding the Retinol binding Protein 4. The human serum or plasma is incubated in the plate with the capture antibody. The specimen is washed out and the specifically bound protein is incubated with biotin labelled detection

The Retinol-Binding Protein 4 (RBP4) ELISA is an enzyme immunoassay for the quantitative determination of Retinol-Binding Protein 4 (RBP4) in human serum and plasma.

The microtiter plate is coated with the antibody specifically binding the Retinol-binding Protein 4. The human serum or plasma is incubated in the plate with the capture antibody. The specimen is washed out and the specifically bound protein is incubated with biotin-labelled detection antibody. Following another washing step, Streptavidin-HRP conjugate is added into the well. Unbound reagent is then washed out. Horseradish peroxidase (HRP) bound in the complex reacts with the chromogenic substrate (TMB) creating the blue colour. The reaction is stopped by addition of STOP solution (H2SO4). The absorbance values are measured at 450 nm (optionally 450/630 nm) and are proportional to the concentration of RBP4 in the specimen. The concentration of RBP4 in unknown samples is determined from the calibration curve which is created by plotting the absorbance values against the standard concentration values.

Highly recommended sunscreen
Goes on clear, is a little bit greasy at first but soaks into the skin fast. Excellent protection from the sun. Not loaded up with all kinds of moisturizers or smelly lotions. I appreciate that.

Best mineral sunscreen
Size: 3.4 Fl Oz (Pack of 1)
Best sunblock. No white cast if you use the 30 spf. My dermatologist recommended this years ago and I’ve used it since.

No white residue
Size: 3.4 Fl Oz (Pack of 1)
I put this sunscreen on immediately after it was delivered. It smells so good & goes on smoothly without any white residue. It seems to protect the skin, but then again I put some on every hour on the hour and didn't have any issues. I will be reordering. I wish this was on subscribe and save, but will continue to purchase.
