The Human IgG3 ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for detection of human IgG3 in plasma, serum, urine, saliva, milk, and cell culture supernatants. This assay employs a quantitative sandwich enzyme immunoassay technique that measures human IgG3 in less than 4 hours. A polyclonal antibody specific for human IgG3 has been precoated onto a 96-well microplate with removable strips. IgG3 in standards and samples is sandwiched by the immobilized antibody and the biotinylated polyclonal antibody specific forIgG3, which is recognized by a streptavidin-peroxidase conjugate
