Assay Method Information

Assay Name:  Pulldown Assay
Description:  Jurkat cells were treated with DMSO or concentration of compound indicated. 6 hours after treatment, cells were washed and harvested by resuspending in lysis buffer (50 mM Hepes pH 7.4, 150 mM NaCl, 1% NP-40, 5 mM EDTA, protease and phosphatase inhibitors) and lysing on ice 30 minutes. Lysates were cleared by centrifugation at 15,000 rpm 30 minutes. Biotin-labeled THZ1 was added to 1 μM to lysates and rotated at 4° C. overnight. Streptavidin-agarose beads were washed and 30 μL slurry was added to each lysate and rotated for 1 hour at 4° C. Beads were washed 5 times with lysis buffer and 50 μL 2×LDS buffer was added to each sample. Samples were boiled and equal volume of protein was loaded onto gel. Gel was transferred to nitrocellulose and blotted for Cyclin K and Cyclin H.
