Western blot analysis of extracts from A431, NIH/3T3, COS and PC12 cells, using Acetyl-CBP (Lys1535)/p300 (Lys1499) Antibody.
Western blot analysis of hypo- or hyper-acetylated recombinant p300 HAT domains, either wild-type or K1499R mutant, using Acetyl-CBP (Lys1535)/p300 (Lys1499) Antibody (upper). Also shown in the corresponding coomassie stained SDS-PAGE gel (lower). (Details are described in Thompson, P.A. et al. (2004) Nat. Struct. Mol. Biol. 11, 308-315.)
Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 10 6 293 cells treated with Forskolin #3828 (30uM) and either 20 μl of Acetyl-CBP (Lys1535)/p300 (Lys1499) Antibody or 2 μl of Normal Rabbit IgG #2729, using SimpleChIP ® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using human ALS2 exon 1 primers, SimpleChIP ® Human NR4A3 Promoter Primers #4829, and SimpleChIP ® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.
