Affinity-purified polyclonal antibody to mouse IgA, IgG, and IgM, both heavy and light chains (whole IgA, IgG, IgM), made in goat, and labeled with alkaline phosphatase. ReserveAP conjugates represent the latest advances in conjugation chemistry and are more sensitive than standard AP conjugates. Product has been cross-adsorbed to human serum to minimize cross-reactivity to human immunoglobulin. Product is in lyophilized form. Each lot is tested to assure specificity and lot-to-lot consistency using an in-house ELISA assay.
