Detects human Reg3A in direct ELISAs and Western blots. In direct ELISAs, approximately 5% cross-reactivity with recombinant human (rh) Reg3G, recombinant mouse (rm) Reg3A, rmReg3B and recombinant rat Reg2 is observed and less than 2% cross-reactivity with rhReg1A, rhReg1B, rmRegIV, rmReg2 and rmReg3D.

Detection of Human Reg3A by Western Blot. Western blot shows lysates of human small intestine tissue. PVDF membrane was probed with 1 µg/mL of Human Reg3A Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5940) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Reg3A at approximately 17 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Reg3A (regenerating gene III alpha ) is a secreted, 17 kDa, type III member of the Reg family, C-type lectin superfamily of proteins. It is expressed in intestine and exocrine pancreas, where it may have a protective effect against infection and TNF-alpha -induced stress. Mature mouse Reg3A is 149 amino acids (aa) in length (aa 27‑175). It is essentially a soluble C-type lectin domain (aa 40‑173). There are four type III genes ( alpha -δ) in the mouse Reg family. Reg3A has less that 60% aa identity to beta -δ. Mature mouse Reg3A is 87% and 61% aa identical to rat and human Reg3A, respectively.
