p27/Kip1 Antibody (KIP1/9168R) Summary

• Description: Store at 2 to 8C. Non-hazardous. No MSDS required.
• Additional Information: Recombinant Monoclonal Antibody
• Immunogen: Recombinant full-length human p27/Kip1 protein
• Localization: Nucleus.
• Specificity: This monoclonal antibody recognizes a 27kDa protein, identified as the p27Kip1, a cell cycle regulatory mitotic inhibitor. It is highly specific and shows no cross-reaction with other related mitotic inhibitors. In Western blotting of cell lysates from 7 human breast cancer cell lines (ZR75-1, ZR75-30, MCF-7, MDAMB453, T47D, CAL51, 734B), the antibody labels a single band corresponding to p27Kip1. It functions as a negative regulator of G1 progression and has been proposed to function as a possible mediator of TGF-i induced G1 arrest.
• Isotype: IgG Kappa
• Clonality: Monoclonal
• Host: Rabbit
• Gene: CDKN1B
• Purity: Protein A purified

Applications/Dilutions

• Dilutions:
  • Immunohistochemistry-Paraffin 1-2ug/ml
• Application Notes: Immunohistochemistry-Paraffin: 1-2ug/ml for 30 minutes at RT. Staining of formalin-fixed tissues requires heating tissue sections in 10mM Tris with 1mM EDTA, pH 9.0, for 45 min at 95C followed by cooling at RT for 20 minutes. Optimal dilution for a specific application should be determined.

Background

p27(Kip1) is a cyclin-dependent kinase inhibitor involved in G1 arrest. p27(Kip1) binds to and inhibits cyclinE-Cdk2 complex, cyclinA-CDK2 and cyclinD1-CDK4 (1). p27(Kip1) is regulated by phosphorylation on serine 10 (S10) and threonine 187 (T187). Phosphorylation by CDK2 on T187 results in ubiquitylation and degradation of p27(Kip1) (2); while phosphorylation by hKIS on S10 signals the nuclear export to the cytoplasm (3).
