Overview

This product has been discontinued.



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.

Recommended reaction conditions
Kinase Activity Assay Required Materials •Assay Buffer: 25 mM β-glycerophosphate, 20 mM Tris-HCl, 5 mM EGTA, 1 mM DTT, pH 7.5 •Substrate: 800 µM RRRDDDSDDD peptide substrate •CKII, α2: 5-10 ng/µl CKII, α2 diluted in Assay Buffer just prior to use •Magnesium/ATP Mix: 75 mM MgCl2, 500 µM ATP •Diluted [γ-32P]ATP/Magnesium/ATP Mix: Mix 197 µl Magnesium/ATP Mix with 3 µl (30 µCi) [γ-32P]ATP (3000 Ci/mmol) Protocol 1. Pipette 10 µl Assay Buffer into a clean microcentrifuge tube on ice. 2. Add 10 µl Substrate. 3. Add 10 µl diluted CKII, α2. 4. Add 10 µl Diluted [γ-32P]ATP/Magnesium/ATP Mix. 5. Incubate at 37° for 10 min. 6. Stop the reaction by placing the tubes on ice. 7. Spot 10 µl of each reaction on P81 paper and allow to bind for 30 s. 8. Wash by immersing the paper in 0.75% phosphoric acid and gently shaking. Repeat for a total of 3 washes. 9. Wash as in step 8 using acetone. 10. Dry using an infrared light. 11. Determine the cpm using a scintillation counter or imager.
