Recombinant Human CDKN1B/p27/K

Recombinant Human CDKN1B/p27/Kip1/Cyclin-dependent kinase inhibitor 1B  (C288)

 

产品说明(Description)

Recombinant Human Cyclin-Dependent Kinase Inhibitor 1B is produced by our E.coli expression system and the target gene encoding Met1-Thr198 is expressed with a 6His tag at the N-terminus. 

Accession #: P46527

Known as: Cyclin-Dependent Kinase Inhibitor 1B; Cyclin-Dependent Kinase Inhibitor p27; p27Kip1; CDKN1B; KIP1

 

制剂（Formulation）

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

 

质量控制（Quality Control） 

 

Purity:            Greater than 95% as determined by reducing SDS-PAGE.    

Endotoxin:    Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.

 

复溶（Reconstitution）

Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 μg/ml.
Dissolve the lyophilized protein in distilled water.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.    

 

保存（Storage）

Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months.     

 

背景（Background）

Cyclin-Dependent Kinase Inhibitor 1B (CDKN1B) is a Kinesin-related motor protein necessary for mitotic spindle assembly and chromosome segregation. CDKN1B is expressed in all tissues with highest levels observed in skeletal muscle. CDKN1B is a potent inhibitor of Cyclin E- and Cyclin A-CDK2 complexes. CDKN1B forms a complex with Cyclin Type D-CDK4 complexes and is involved in the assembly, stability, and modulation of CCND1-CDK4 complex activation. In addition, CDKN1B acts as an inhibitor or an activator of Cyclin Type D-CDK4 complexes depending on its phosphorylation state and stoichometry.
