The ChIPAb+ Acetyl-Histone H3 (Lys9) set includes the anti-acetyl-histone H3 (Lys9) antibody, a negative control antibody (purified Rabbit IgG), and qPCR primers flanking an Sp1 binding site in the human p21 (WAF1/CIP1/CDKN1A) promoter, amplifying a 105 base pair PCR product. The acetyl-histone H3 (Lys9) and negative control antibodies are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of acetyl-histone H3 (Lys9) associated chromatin.
