Rabbit Anti-PHAP I, IN (Putative HLA DR-associated Protein)
Apoptosis is related to many diseases and development. Caspase-9 plays a central role in cell death induced by a variety of apoptosis activators. Cytochrome c, after released from mitochondria, binds to Apaf-1, which forms an apoptosome that in turn binds to and activate procaspase-9. Activated caspase-9 cleaves and activates the effector caspases (caspase-3,-6 and –7), which are responsible for the proteolytic cleavage of many key proteins in apoptosis. The tumor suppressor putative HLA-DR-associated proteins ( PHAPs ) were recently identified as important regulators of mitochondrion apoptosis (1). PHAP appears to facilitate apoptosome-medicated caspase-9 activation and to stimulate the mitochondrial apoptotic pathway. PHAP was also shown to oppose both Ras and Myc-mediated cell transformation.
Applications
Suitable for use in ELISA, Western Blotting. Other applications not tested.
Recommended Dilution
Western Blotting: 2-4ug/ml. Raji cell lysate can be used as a positive control and a band at approximately 32kD can be detected
Optimal dilutions to be determined by the researcher.
Blocking peptide: P3368-03A
Positive Control: Raji cell lysate
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%). Freeze at -20°C. 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.
Immunogen
Synthetic peptide corresponding to amino acids close to C-terminus of human PHAP I (1). This sequence is identical between human and rat PHAP I.
Form
Supplied as a liquid in PBS, pH 7.2, 0.02% sodium azide.
Purity
Purified by immunoaffinity chromatography.
Specificity
Detects PHAP I. Species Crossreactivity: human and rat PHAP I.
