Casein Kinase II, α2, Active, Human, Recombinant, E. coli
Recombinant, human casein kinase II, α2, (CKII, α2) fused to maltose binding protein (MBP) at the N-terminus and expressed in E. coli. CKII, α2 is a catalytic subunit of the serine/threonine protein kinase CKII. It is suitable for use in reactions where autophosphorylation of the regulatory CKII β-subunit is not desired. Shown to be extremely salt-sensitive with respect to its activity.
