Detection of Reg1A in AGS Human Cell Line by Flow Cytometry. AGS human gastric adenocarcinoma cell line was stained with Rat Anti-Human Reg1A Alexa Fluor® 488-conjugated Monoclonal Antibody (Catalog # IC4937G, filled histogram) or isotype control antibody (Catalog # IC0041G, open histogram). Cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005).

Background: Reg1A

Human Reg1A, also known as Reg1 alpha, PTP, PSP and Lithostathine, is a 16-22 kDa, variably glycosylated member of the Reg (Regenerating) family, C-type lectin superfamily of molecules. It is further classified as a type I subfamily member based on gene organization and expression pattern. These are four Reg subfamilies spread across multiple species, with three (or four) additional human Reg family genes assigned to three of the subfamilies. Reg1A is secreted, and circulates as either a monomer, dimer, or tetramer. Once secreted, Reg1A may undergo proteolysis with removal of the N-terminal 11 amino acids (aa). This renders it insoluble with subsequent fibril formation. Reg1A is typically inducible, and human cells reported to express Reg1A include pancreatic islet beta -cells, neurons, intestinal Paneth cells, stomach Chief cells, cardiomyocytes, salivary duct epithelium and antral endocrine cells of the stomach. Reg1A has proliferative effects on multiple cell types, and likely serves as an anti-inflammatory agent. This is presumably mediated by binding to its receptor, EXTL3. Mature human Reg1A (aa 23-166) shares 75%, 69% and 88% aa sequence identity with mouse RegI,rat Reg, and human Reg1B, respectively.
