Anti-REG4 Antibody

REG4 (Regenerating Islet-Derived Protein 4) is a secreted C-type lectin expressed predominantly in epithelial cells of the gastrointestinal tract, with elevated levels implicated in mucosal repair, inflammatory signaling, and several solid tumor contexts including gastric, pancreatic, and colorectal carcinomas. This rabbit polyclonal reagent from Antibodies.com is raised against REG4 and validated for Western blot detection of the human, mouse, and rat orthologs, supporting translational studies that span rodent disease models and patient-derived samples.

Supplied as 100 µl of unconjugated Ig at 1 mg/ml in phosphate buffered saline (pH 7.2) containing 15 mM sodium azide as preservative, the antibody is ready to dilute into standard blocking buffers for immunoblotting. Aliquot upon first use, refrigerate, and protect from light; avoid repeated freeze-thaw cycles to preserve titer across multiple experiments. The polyclonal format yields broader epitope coverage, useful when probing full-length REG4 or detecting potential splice variants.
