CST, 45506SF, PCAF (C14G9) Rabbit Monoclonal Antibody (BSA and Azide Free)

Monoclonal Antibody for studying PCAF. Validated for Western Blotting. Highly specific and rigorously validated in-house, PCAF (C14G9) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #45506) is ready to ship. Product Usage Information This product is the carrier free version of product #3378. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol. This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN or CUT&Tag assays. If you require a carrier free formulation for chromatin profiling, please contact us . Optimal dilutions/concentrations should be determined by the end user. BSA and Azide Free antibodies are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity. Formulation Supplied in 1X PBS (10 mM Na 2 HPO 4 , 3 mM KCl, 2 mM KH 2 PO 4 , and 140 mM NaCl (pH 7.8)). BSA and Azide Free. For standard formulation of this product see product # 3378 Storage Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance. Specificity / Sensitivity PCAF (C14G9) Rabbit Monoclonal Antibody (BSA and Azide Free) detects endogenous levels of total PCAF protein. This antibody does not cross-react with the related GCN5L2 protein. Species Reactivity: Human, Mouse, Rat, Monkey Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to the amino terminus of human PCAF protein. Background p300/CBP-associated factor (PCAF), also known as lysine acetyl-transferase 2B (KAT2B), is a transcriptional adaptor protein and histone acetyl-transferase (HAT) that functions as the catalytic subunit of the PCAF transcriptional co-activator complex (1). PCAF is 73% homologous to GCN5L2, another HAT protein found in similar complexes (1,2). Like GCN5L2, PCAF acetylates histone H3 on Lys14 and histone H4 on Lys8, both of which contribute to gene activation by modulating chromatin structure and recruiting additional co-activator proteins that contain acetyl-lysine binding bromo-domains (3). PCAF also acetylates non-histone proteins including transcriptional activators (p53, E2F1, MyoD), general transcription factors (TFIIEβ and TFIIF) and architectural DNA binding proteins (HMGA1 and HMG17) (4-10). Acetylation of these proteins regulates their nuclear localization, protein stability, DNA binding, and co-activator association.
