Product Description specificalIntended Uses: For the qualitative determination of activated Human Cytomegalovirus IgA Antibody (CMV-IgA) in serum, plasma, tissue homogenate, cell culture supernates and other biological fluids.
Principle of the Assay||The kit uses a double-antigen sandwich enzyme-linked immunosorbent assay (ELISA) to analyze the existence or not of Human CMV-IgA in samples. Add sample to wells pre-coated with one Human Cytomegalovirus IgA antigen, at same time add HRP-conjugated Human Cytomegalovirus IgA antigen to bind the analyte, followed by incubation and washing procedures to remove unbound substance. Finally, HRP substrates are added, incubated for detection, and a blue color is developed. Reaction is stopped and color turns to yellow when Stopping Solution (acidic) is added. The existence or not of Human CMV-IgA in the samples is then determined by comparing the O.D. of the samples to the CUT OFF.
