Apoptosis, or programmed cell death, is related to many diseases, such as cancer.
Apoptosis is triggered by a variety of stimuli including members in the TNF family and can be prevented by the inhibitor of apoptosis (IAP) proteins.
IAP proteins form a conserved gene family that binds to and inhibits cell death proteases (1 for review).
The X-chromosome linked inhibitor of apoptosis (XIAP) contains 3 baculoviral IAP repeat (BIR) motifs that are essential and sufficient for the binding and inhibition of caspases–3, –7, and –9 (2,3).
Upregulation of XIAP expression can protect cells from apoptosis induced by low level radiation; conversely, decreased XIAP expression by antisense targeting resulted in increased cell death following low level radiation (4).
Two negative regulators, termed XAF-1 (5) and Smac (6), can bind and inhibit XIAP activity.
Applications:Can be used for the detection of XIAP by Western blot at 0.5 to 2ug/ml.
Human kidney cell lysate can be used as positive control.
Storage and Stability:May be stored at 4°C for short-term only.
For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%).
Store at -20°C or colder.
Aliquots are stable for at least 12 months at -20°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.
