Western blot analysis of p57[Kip2]. Lane 1, SJCRH30 human rhabdomyosarcoma cell lysate was probed with anti-p57[Kip2]. In lane 2, mouse IgG1 isotype (negative) control. p57[Kip2] is identified as an ~57 kDa doublet.

Regulatory Status Legend
Any use of products other than the permitted use without the express written authorization of Becton, Dickinson and Company is strictly prohibited.
Preparation And Storage
Recommended Assay Procedures
Applications for clone A120-1 include western blot analysis (1-2 µg/ml). SJCRH30 human rhabdomyosarcoma cells are suggested as a positive control (ATCC CRL-2061).
Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
Cyclin dependent kinase inhibitors (CdkIs) inhibit progression through the cell cycle by binding to cyclins, Cdks, or cyclin-Cdk complexes. CdkIs are classified into two groups based on protein structure. p57[Kip2] belongs to a group that also includes p27[Kip1] and p21 (also known as Sdi1, Cip1, Waf1 and Pic1). Members of this group have a homologous amino-terminal Cdk inhibitory domain. Members of the second group [p16 (INK4A), p15 (INK4B), p18 (INK4C), and p19 (INK4D)] contain ankyrin repeat motifs. p57[Kip2] is a potent, tight-binding inhibitor of several G1 and S phase cyclin-Cdk complexes including cyclin E-Cdk2, cyclin D2-Cdk4, and cyclin A-Cdk2. It inhibits the mitotic cyclin B1-Cdk1 complex to a lesser extent. mRNA studies suggest that p57[Kip2] expression is tissue-specific, the highest levels have been found in embryonic and adult skeletal muscle, heart, kidney, lung, eye and brain. This is in contrast to the widespread tissue expression of p27[Kip1] and p21 mRNA. The expression of p57[Kip2] to primarily terminally differentiated cells suggests that p57[Kip2] may play a specialized role in cell cycle control. Clone A120-1 reacts with human p57[Kip2]. Recombinant human p57[Kip2] was used as immunogen.
