Description
Principle of the Assay: The Picokine Human Serpin A1 Pre-Coated ELISA (Enzyme-Linked Immunosorbent Assay) kit is a solid phase immunoassay specially designed to measure Human Serpin A1 with a 96-well strip plate that is pre-coated with antibody specific for Serpin A1. The detection antibody is a biotinylated antibody specific for Serpin A1. The capture antibody is a monoclonal antibody from mouse, the detection antibody is a biotinylated polyclonal antibody from goat. The kit contains recombinant Human Serpin A1 with immunogen: Expression system for standard: NSO,E25-K418. The kit is analytically validated with ready to use reagents. To measure Human Serpin A1, add standards and samples to the wells, then add the biotinylated detection antibody. Wash the wells with PBS or TBS buffer, and add Avidin-Biotin-Peroxidase Complex (ABC-HRP). Wash away the unbounded ABC-HRP with PBS or TBS buffer and add TMB. TMB is substrate to HRP and will be catalyzed to produce a blue color product, which changes into yellow after adding acidic stop solution. The density of the yellow product is linearly propotional to Human Serpin A1 in the sample. Read the density of the yellow product in each well using a plate reader, and benchmark the sample wells' readings against the standard curve to determine the concentration of Human Serpin A1 in the sample:
