Background Information
Poly(ADP-ribosyl)ation is a post-translational modification of proteins mediated by one of the 17 members of the poly(ADP-ribose) polymerases (PARP). PARP-9 belongs to the subfamily of macroPARPs, associating one to three macro domains to the PARP domain. Overexpression of PARP-9 stimulates cell migration in vitro, suggesting a role for PARP-9 in the promotion of malignant B cell migration and dissemination in high risk DLBCL. PARP-9 is also likely a transcription coactivator, its overexpression in B lymphocytes, stimulated by IFNγ, inducing the transcription of IFNγ-controlled genes.

Reviews
What customers say
Both reviewers report positive experiences with this antibody. One user (4/5) found it a good working antibody for Western Blot at 1:800 dilution on HEK293 and U2OS cells. The other (5/5) described it as a "game changer" for detecting PARP9 signals, noting that other PARP9 antibodies had failed where this one succeeded. It performed well at 1:500 dilution in both short (1.5–2 hr) and overnight incubations across multiple mammalian cell lines including HeLa and HNSCC. Overall, users highlight its strong sensitivity and reliability for PARP9 detection.

Lisa (Verified Customer) (07-23-2025) | Good working antibody for WB.
|
Hadil (Verified Customer) (05-25-2023) | I have had trouble detecting PARP9 signals with other PARP9 antibodies, however, this antibody is a game changer. It works well both at room temperature (1.5 -2 hrs) and also overnight at 1:500 dilution. Would highly recommend to anyone who's studying PARP9.
