recombinant protein

Cdk5/p25, active

Background

CDK5 is a member of the Cyclin-Dependent Kinase family that is most abundant in the mammalian brain. This recombinant product is a complex of human Cdk5 and C-terminal His-tagged C-terminal p25 fragment of human p35, and was expressed in Sf9 insect cells by baculovirus.

Formulation

10mM MOPS (pH6.8), 0.1M NaCl, 1mM MgCl2, 0.5% Nonidet P-40, 1mM DTT, 10% glycerol, 0.4mM Pefabloc, 1 μM E64.

Specific Activity

500 U/mg, where one unit of cdk5/p25 activity is defined as 1 nmol phosphate incorporated into 0.1 mg/ml Histone H1 per minute at 35 degrees with a final ATP concentration of 100 μM.

  • Psoralen with a delivery peptide biotinylated [CSR-NIG-L1-R1]
    The psoralen reagent was further improved by replacing a linker region between psoralen and biotin with a delivery peptide derived from HIV Tat protein.This allows rapid incorporation of the reagent into cells without prior treatment with a detergent. The method is applicable to cultured cells, tissue slices and dissected out small tissues where transcription is going on
