Human PARP ELISA Kit (Colorimetric) Summary

Description
The stop solution changes color from blue to yellow and the intensity of the color is measured at 450 nm using a spectrophotometer. In order to measure the concentration of Human PARP in the sample, this Human PARP ELISA Kit includes a set of calibration standards. The calibration standards are assayed at the same time as the samples and allow the operator to produce a standard curve of optical density versus Human PARP concentration. The concentration of the samples is then determined by comparing the O.D. of the samples to the standard curve.

Background

Poly (ADP-ribose) polymerase (PARP) is protein family primarily invloved in DNA repair and programmed cell death. PARP proteins are activated in response to DNA single strand breaks (SSBs). Upon SSB detection, PARP binds the DNA and synthesizes a PAR chain at the damaged site, which then signals the initiation of DNA repair by other enzymes such as XRCC1, DNA ligase III and DNA polymerase beta. After repair, the PAR chains are degraded via PAR glycohydrolase.

PARP is inactivated by caspase cleavage, leading to a programmed cell death pathway.

Limitations

FAQs for PARP ELISA Kit (NBP3-18217). (Showing 1 - 2 of 2 FAQ).

  1. I was wondering if you would mind letting me know which product would you recommend for immunochemistry of the retina of the rat and mouse by poly (ADP-ribose) polymerase (PARP) and calpain. There are many different calpain antibodies in your website. The samples are 12-um vertical cryostst sections (fixed by PFA).
    • For PARP, I would recommend either NB120-2168 or NB100-64828. Bear in mind that they are both mouse monoclonals, and you may have to take extra steps to reduce mouse-on-mouse background.
  2. Do you have any 100 coda or bigger controls?
    • I can recommend a couple of high weight antibodies that are conserved in most samples. Please verify the presence of the protein before using as a loading control. PARP1 or PARP is approximately 113kDa, and you may view the products we offer to PARP using this link. Vinculin is approximately 116kDa, and you may view the products we offer to Vinculin using this link.
