CST, 49248SF, p63-alpha (D2K8X) Rabbit Monoclonal Antibody (BSA and Azide Free)

Monoclonal Antibody for studying p63. Validated for Western Blotting,Immunofluorescence (Immunocytochemistry),Flow Cytometry (Fixed/Permeabilized). Highly specific and rigorously validated in-house, p63-alpha (D2K8X) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #49248) is ready to ship. Product Usage Information This product is the carrier free version of product #13109. 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 # 13109 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 p63-alpha (D2K8X) Rabbit Monoclonal Antibody (BSA and Azide Free) recognizes endogenous levels of total p63-α protein. This antibody will detect both the full-length isoform (TAp63-α) and the truncated δNp63-α isoform, but will not recognize the p63-β or p63-γ isoform. Species Reactivity: Human Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human p63-α protein. Background The p53 tumor suppressor protein plays a major role in cellular response to DNA damage and other genomic aberrations. Activation of p53 can lead to either cell cycle arrest and DNA repair or apoptosis (1). In addition to p53, mammalian cells contain two p53 family members, p63 and p73, which are similar to p53 in both structure and function (2). While p63 can induce p53-responsive genes and apoptosis, mutation of p63 rarely results in tumors (2). Research investigators frequently observe amplification of the p63 gene in squamous cell carcinomas of the lung, head and neck (2,3). The p63 gene contains an alternative transcription initiation site that yields a truncated ΔNp63 lacking the transactivation domain, and alternative splicing at the carboxy-terminus yields the α, β, and γ isoforms (3,4).
