Description
27-OHC (27-Hydroxycholesterol) ELISA KitThis 27 OHC (27 Hydroxycholesterol) ELISA Kit is based on Competitive ELISA detection method and takes 2h assay time. The microplate provided in this kit has been precoated with 27 OHC. 27 OHC in the sample or standard competes with a fixed amount of biotin labeled 27 OHC for sites on a pre coated antibody specific to 27 OHC. Free components are washed off. After adding HRP Streptavidin Conjugate (SABC), biotin specifically binds with streptavidin to
This 27-OHC (27-Hydroxycholesterol) ELISA Kit is based on Competitive-ELISA detection method and takes 2h assay time. The microplate provided in this kit has been precoated with 27-OHC. 27-OHC in the sample or standard competes with a fixed amount of biotin-labeled 27-OHC for sites on a pre-coated antibody specific to 27-OHC. Free components are washed off. After adding HRP-Streptavidin Conjugate (SABC), biotin specifically binds with streptavidin to form immune complexes. Wash off unbound conjugate. Add TMB substrate solution. Then, TMB was catalyzed by HRP to produce a blue color product that turned yellow after adding a stop solution. Read the O.D. absorbance at 450nm in a microplate reader. Compare OD450 value of sample with the standard curve through curve fitting software to determine the concentration of 27-OHC in the sample. The concentration of the target substance is inversely proportional to the OD450 value.
