Gene Symbols: MICA, PERB11.1
Background: The S-Acylated MICA ELISA Kit uses a modified "biotin-switch" method to allow for the direct visualization of human S-Acylated MICA by ELISA. In this S-Acylation biotin switch assay, unmodified free cysteines are first blocked. S-Acylated cysteines are then selectively reduced for specific labeling with biotin-maleimide reagents, which irreversibly bind to the cysteine thiol that was S-Acylated. Biotinylation of the newly formed thiol groups can then be detected by ELISA. An anti-pan MICA antibody has been coated onto a 96-well plate. Biotinylated samples are pipetted into the wells, and MICA present in a sample is bound to the wells by the immobilized antibody. The wells are washed, and HRP-conjugated streptavidin is used to detect S-Acylated MICA. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of S-Acylated MICA bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
