The ELISA kits listed below target CD22, the symbol for the human gene, CD22 molecule, and a member of the Immunoglobulin superfamily, SIGLEC (sialic acid binding Ig-like lectin) family. The protein encoded by CD22 has a predicted amino acid length of 847, a mass of 95.3 kDa, and a membrane subcellular localization. There are currently 5 reported isoforms, as well as sites of glycosylation. CD22 may also be known by the following names: SIGLEC-2, sialic acid-binding Ig-like lectin 2, CD22 antigen, BL-CAM, B-lymphocyte cell adhesion molecule, and B-cell receptor CD22. Orthologs of the gene, including human, mouse, rat, bovine, primate, guinea pig, and other mammalian are available targets of several ELISA kits.
