Description_x000D_ General description_x000D_ Recombinant P/CAF is useful in HAT inhibitor screening, kinetic studies and HAT substrate cleavages in vitro or in tissue culture. P/CAF can also be used as positive control in HAT activity assay. The recombinant P/CAF (p300/CBP-associated factor) encoding human sequence from 492 to 658 of accession number Q92831 was produced from E. coli and then purified by several chromatographic steps._x000D_ Physical form_x000D_ Lyophilized powder_x000D_ Reconstitution_x000D_ Centrifuge the vial prior to opening. Reconstitute in MilliQ H2O to a concentration of 1 mg/ml. The solution can then be used in bioassay, or store at -20°C for future use.
