Human proteins, cDNA and human recombinants are used in human reactive ELISA kits and to produce anti-human mono and polyclonal antibodies. Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens). Depending on the epitopes used human ELISA kits can be cross reactive to many other species. Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples.Immunoglobulin A (IgA, also referred to as sIgA) is an antibody that plays a critical role in immune function in the mucous membranes. More IgA is produced in mucosal linings than all other types of antibody combined. Examples are EMA, ACA ELISA test kits and for diagnostic detection the IgA of Anti-Beta-2 Glycoprotein 1; β2-Glycoprotein 1 Antibodies; Beta 2GP1 Ab, Beta-2 Glycoprotein 1 Antibodies IgG, IgM, and IgAs.
