C8471-61C
CDKN1B (Cyclin-dependent Kinase Inhibitor 1B, Cyclin-dependent Kinase Inhibitor p27, p27Kip1, KIP1)
Description:
CDKN1B is a cyclin-dependent kinase inhibitor, which shares a limited similarity with CDK inhibitor CDKN1A/p21. The encoded protein binds to and prevents the activation of cyclin E-CDK2 or cyclin D-CDK4 complexes, and thus controls the cell cycle progression at G1. The degradation of this protein, which is triggered by its CDK dependent phosphorylation and subsequent ubiquitination by SCF complexes, is required for the cellular transition from quiescence to the proliferative state.

Applications:
Suitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications not tested.

Recommended Dilution:
ELISA: 1:32,000
Western Blot: 0.1-0.3ug/ml, observed in lysates of human prostate and of hepatoblastoma cell line HepG2 on ~26kD bands
Immunohistochemistry (Paraffin): 5-10ug/ml
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
