CK2h Human
Casein Kinase 2 Holoenzyme Human Recombinant
Catalog No. PKA-211
Synonyms:
Casein Kinase 2 Holoenzyme, CK2h.
Description:
Human recombinant casein kinase 2 holo enzyme containing alpha and beta subunits which were separately expressed in E. coli as non-fusion proteins and purified using several chromatographic steps. The holo enzyme has been reconstituted in the course of the purification and is highly active suitable for labelling CK2 substrates. CK2 holoenzyme is a non-glycosilated polypeptide having a molecular mass of 140 kDa.
Source:
Escherichia Coli.
Physical Appearance:
Sterile Filtered clear solution.
Formulation:
CK2 Holoenzyme is supplied 0.5mg/1ml in 25mM Tris-HCl, 500mM NaCl, 1mM DTT, 500 µM PMSF, 5% glycerol, pH 8.5.
Unit Definition:
No protease activity detectable, specific activity > 1.3U/mg
(1U = 1µmol/min at 37 degree C) using the synthetic peptide RRRDDDSDDD.
Storage Conditions:
Store at 4°C if entire vial will be used within 2-4 weeks.
Store, frozen at -20°C for longer periods of time.
