IMPORTANT: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Regenerating islet-derived protein 3 alpha (Reg3A), formerly known as HIP/PAP (Hepatocarcinoma-Intestine-Pancreas/Pancreatitis-Associated Protein) and peptide 23, is a pancreatic secretory protein that may be involved in cell proliferation or differentiation. Increases of Reg3A were observed during pancreatic inflammation and liver carcinogenesis. Reg3A is also a bactericidal C-type lectin that is constitutively produced in the intestine and has antibacterial properties against Gram-positive bacteria mediated by binding to surface-exposed carbohydrate moieties of bacterial peptidoglycan.
Diseases associated with REG3A include Pancreatitis and Acute Pancreatitis.
