Detection of Reg1A in AGS Human Cell Line by Flow Cytometry. AGS human gastric adenocarcinoma cell line was stained with Rat Anti-Human Reg1A Monoclonal Antibody (Catalog # MAB4937, filled histogram) or isotype control antibody (Catalog # MAB0061, open histogram), followed by Allophycocyanin-conjugated Anti-Rat IgG F(ab')2 Secondary Antibody (Catalog # F0113). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.

Reg1A, also known as PTP, PSP, and lithostathine, is a member of the Reg family of secreted proteins with a C-type lectin domain. Due to variable glycosylation, pancreatic Reg1A exists as multiple species of 16‑18 kDa. Reg1A promotes the maintenance and growth of pancreatic islet beta -cells and intestinal villi. It is up‑regulated in pancreatitis and some carcinomas. Reg1A is an antigenic target in autoimmune diabetes. Human Reg1A shares 65%‑68% aa sequence identity with mouse and rat Reg1A.
