PARP1

Further unraveling the role of gamma H2AX in DNA damage response

Our genome experiences a moderate amount of DNA damage in our cells on a daily basis.  This DNA damage can be in response to external environmental factors, or be a result of our internal metabolic processes going awry.  While normal rates of DNA damage are not an immense threat to our cell processes, DNA damage in critical genes can lead to a variety of disease, including cancer and tumor formation.   After induction of DNA damage (for example, in the form of double strand breaks), phosphorylation and recruitment of the H2AX protein occurs.  This phosphorylation produces gamma H2AX

PARP Antibody Assays aid both Apoptosis and Cancer Research

The PARP (Poly(ADP-ribose) polymerase) protein is a zinc-dependant nuclear enzyme whose main role is to detect and repair DNA single-strand breaks (SSB). However, PARP antibody research has revealed there are at least 17 PARP proteins, which also play a major role in apoptosis (programmed cell death) and post-translational modification. We at Novus Biologicals have an extensive range of PARP antibody products in our antibody catalogu.
