Anti-SARNP Antibody

Rabbit polyclonal reagent raised against SARNP, the SAP domain-containing ribonucleoprotein also referenced as CIP29 and HCC1, supplied by Antibodies.com as a 100 µl aliquot at 1 mg/ml in phosphate buffered saline with 0.05% sodium azide at approximately pH 7.2. The unconjugated antibody was generated in rabbit and validated for western blot and immunocytochemistry (ICC), with reactivity confirmed against human, mouse, and rat samples, supporting cross-species work in cell biology labs studying RNA metabolism.

SARNP participates in mRNA export from the nucleus and has been linked to proliferation control and stress responses, with documented roles in hepatocellular carcinoma and other tumor contexts. Researchers use this reagent to probe endogenous SARNP levels in whole-cell lysates by western blot and to localize the protein within fixed cells by immunocytochemistry. The polyclonal format provides multiple epitope recognition, helpful when a single monoclonal epitope may be obscured by post-translational modification or binding partners. Refrigerate the vial upon receipt; for longer holding, aliquot and freeze at -20 °C to limit freeze-thaw cycles of the antibody solution, and protect from light to preserve the unconjugated preparation.
