Description
Principle of the Assay: This kit was based on sandwich enzyme-linked immune-sorbent assay technology. SM-Lmod was pre-coated onto 96-well plates. And the Biotin- labeled SM-Lmod was used as detection antigen. The standards, test samples and Biotin- labeled SM-Lmod were added to the wells subsequently, and wash with wash buffer. HRP-Streptavidin Conjugate was added and unbound conjugates were washed away with wash buffer. TMB substrates were used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the ASMA amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of ASMA can be calculated
