The Antibodies.com Anti-PIGR Antibody [7C1] is a rat monoclonal IgG1 reagent raised against the polymeric immunoglobulin receptor (PIGR), a transmembrane glycoprotein that mediates transcytosis of polymeric IgA and IgM across mucosal epithelium and gives rise to the secretory component found in mucosal secretions. This unconjugated clone is supplied as 100 µg in liquid format and is validated for immunohistochemistry and western blot on human and mouse samples, supporting studies of epithelial transport, mucosal immunity, and secretory component biology. Shipped in a single vial; store at -20 °C in working aliquots to limit freeze-thaw cycles. For research use only.
