Anti-CGR19 Antibody

The Antibodies.com Anti-CGR19 reagent is a rabbit polyclonal primary antibody that recognizes the Cell Growth Regulator with RING finger domain 1 (CGRRF1) protein, a RING-domain E3 ubiquitin ligase implicated in cell-cycle progression, senescence bypass, and tumor proliferation in epithelial tissues. Raised in rabbit and supplied as an unconjugated IgG preparation, the antibody is provided in a 100 µl volume and validated for Western blot and ELISA workflows on human samples. The polyclonal format increases the chance of recognizing multiple epitopes on CGR19, which is helpful when probing low-abundance targets or detecting alternative splice isoforms. Investigators working on gastric, colorectal, and hepatocellular carcinoma pathways use this reagent to monitor CGR19 expression following gene knockdown or chemotherapeutic challenge, and the unconjugated format allows flexible pairing with HRP, fluorescent, or biotinylated secondary reporters chosen by the end user. Aliquoting upon arrival and storage at -20 °C preserves antibody activity across repeated freeze-thaw cycles, and the reagent is intended for research use only.
