Anti-SRPRB Antibody

Polyclonal rabbit IgG from Antibodies.com targets SRPRB, the beta subunit of the signal recognition particle (SRP) receptor, a resident endoplasmic reticulum membrane protein that mediates cotranslational translocation of nascent secretory and membrane-targeted proteins. Supplied unconjugated at 100 µL per vial, the reagent is validated for western blot and immunohistochemistry on human samples and serves as a marker of the ER translocation machinery. Polyclonal reactivity supports detection of the native antigen across denaturing gel-based western blot workflows and formalin-fixed tissue sections in immunohistochemistry, allowing researchers to monitor SRPRB expression in cell lines and primary tissue. Aliquot upon receipt to limit freeze-thaw exposure, and store at -20 °C to preserve antibody activity over multiple experiments.
