Anti-CBX5 Antibody

This Rabbit polyclonal antibody to chromobox homolog 5 (CBX5), also known as Heterochromatin protein 1 homolog alpha (HP1α), is offered by Antibodies.com under catalog number A34214 and is supplied as a 50 µl volume at a working concentration of 1.0 mg/mL. The reagent is unconjugated and was raised against a recombinant human CBX5 immunogen, then affinity-purified to ensure specificity for the endogenous total CBX5 protein. It is formulated in phosphate-buffered saline at pH 7.4 with 150 mM NaCl, 0.02% sodium azide, and 50% glycerol as a cryoprotectant. For routine handling, the vial is shipped cold at 4 °C; on arrival it should be aliquoted and stored at –20 °C, with repeated freeze/thaw cycles avoided to preserve activity. Validated applications include Western blot (WB) and immunocytochemistry/immunofluorescence (ICC/IF), and the antibody has been verified to react with human and rat samples, making it suitable for chromatin, epigenetics, and nuclear architecture studies in established cell models. As a research-use-only reagent from a polyclonal host, it provides broad epitope coverage for detecting HP1α in chromatin fractionation and heterochromatin marker analyses.
