Overview

  • Product name

    p53 Mediated Apoptosis WB Cocktail
  • Species reactivity

    Reacts with: Human
  • Product overview

    The p53-Mediated Apoptosis Cocktail is designed to study the induction of p53-mediated apoptosis in response to various stimuli.  The two main components of this cocktail are monoclonal antibodies specific to PARP (cleaved) and p53 (phosphorylated at serine 46).  The GAPDH antibody is provided as a loading control for sample to sample normalization.  Since the primary antibodies are both mouse and rabbit, the cocktail of HRP-conjugated goat anti-rabbit and anti-mouse secondary antibodies is provided for convenience.  The targets are easily resolved by Western blot given their different molecular weights.

  • Notes

    Poly [ADP-ribose] polymerase 1 (PARP) is a DNA repair enzyme that is cleaved during apoptosis by activated caspases.  The mouse PARP antibody of this cocktail detects only the apoptosis-specific 89 kDa PARP fragment (cleaved-PARP).  This antibody does not react with the full-length PARP.  The tumor suppressor protein p53 is an important component in the regulation of cellular growth.  p53 regulates the cellular response to DNA damage and other forms of cellular stress by inducing activation of genes involved in DNA repair, cell cycle control, and apoptosis.  Phosphorylation of p53 at serine 46 is a critical part of p53-mediated apoptosis, allowing for the induction of various pro-apoptotic genes.
