Anti-Haptocorrin antibodies are used in antigen-specific immunodetection in biological samples. The target Haptocorrin is a known alias name of the protein transcobalamin 1, encoded by the TCN1 gene in humans. This 433-amino acid residue protein is known to bind vitamin B12 with femtomolar affinity and protects it from the acidic environment of the stomach. The protein is secreted and features glycosylated post-translational modifications. Other synonyms for Haptocorrin include HC, HC, and TC-1. Indicated applications for Haptocorrin antibodies listed below include ELISA, Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry.
