Casein Kinase II, Human, Recombinant, E. coli
Recombinant, human casein kinase II expressed in E. coli. A cyclic nucleotide-independent serine/threonine protein kinase composed of catalytic α-subunits (M.W. 44 kDa) and regulatory β-subunits (M.W. 26 kDa) in an α2β2-tetramer. This material corresponds to one of several forms of native CKII. Suitable for in vitro phosphorylation of proteins and peptides, phosphopeptide synthesis, characterization of phosphorylating sites, screening of activators and inhibitors, and mechanistic studies. Note: 1 KU = 1000 units.
