: Recognizes the p21CIP1 (CDKN1) protein
: Western blot human p21CIP1
p21CIP1 from other species may also be detectable
: Synthetic peptide corresponding to amino acids 143-147 of human p21CIP1
: PBS, pH7.4, 0.02%NaN3, 50% glycerol
: Affinity Chromatography
: Store at 4o
C (add 0.1% NaN3
) for several months, and at -20o
C for longer periods.
For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For optimal performance, avoid repeated handling and multiple freeze/thaw cycles.
: CIP1 (Cyclin-Dependent Kinase Inhibitor 1A) regulates cell cycle progression, terminal differentiation, and apoptosis (1). CIP1 was shown to be induced by p53 and to be a potent inhibitor of cyclin-dependent kinase (CDK) activity. DNA damage leads to increased expression of CIP1 in cyclin E-containing complexes and to an associated decrease in cyclin-dependent kinase activity. CIP1 is a critical downstream effector in the p53-specific pathway of growth control in mammalian cells (2).
