Product Overview
This rabbit polyclonal antibody targets death domain-associated protein 6 (gene DAXX) in human, mouse and rat samples and is validated for flow cytometry, ICC/IF, IHC and Western blot. The predicted molecular weight is 81.4 kDa, and the supplier reports an observed band at about 115 kDa.
DAXX (death domain-associated protein 6) is a nuclear protein that often localizes to PML nuclear bodies and acts as a transcriptional corepressor. Together with ATRX it serves as a chaperone that deposits the histone variant H3.3 at telomeres and pericentromeric chromatin, and it also helps control MDM2 and p53 stability. DAXX is studied in chromatin biology, apoptosis and the DNA damage response.
