Smac/DIABLO, a mitochondrial protein, activates various forms of apoptosis. This activation may be due to the neutralization of one or more members of the IAP family of apoptosis inhibitory proteins. Smac exits the mitochondria and enter the cytosol during certain apoptosis triggered events. Mitochondrial-mediated apoptosis is important in animal development and tissue homeostasis, with alterations resulting in a range of malignant disorders. Upon apoptotic stimuli, the mitochondrial proteins cytochrome c and Smac/DIABLO are released into the cytosol. The release of these proteins, however, occurs via different mechanisms (2,3).
Suitable for use in Western Blot and Immunoprecipitation. Other applications not tested.
Western Blot: 1:500. Detects a band at ~25kD representing Smac/DIABLO. For better results, IP prior to Western Blot is recommended.
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 and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and 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.
