Protein kinase, interferon-inducible double stranded RNA dependent activator (PACT, PRKRA) is a proapoptotic cellular protein activator of PKR, a double-stranded RNA-dependent protein kinase (1). PACT is reported to be stress-activated, and a physiologic activator that couples transmembrane stress signals and protein synthesis (2). Overexpression of PACT in cells causes enhanced sensitivity to stress-induced apoptosis. It is expressed at high levels in colonic epithelial cells, especially as they exit the cell cycle and enter an apoptotic program (3).
Suitable for use in Western Blot, Immunohistochemistry. Other applications not tested.
Western Blot: 1:1000-1:5000
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage, store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
