Human Reg3A Antibody Summary

Species Reactivity
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.
Polyclonal Sheep IgG
Antigen Affinity-purified
E. coli-derived recombinant human Reg3A

Scientific Data

Western Blot Detection of Human Reg3A antibody by Western Blot. View Larger

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.

Background: Reg3A

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.
