CST, 72338SF, FoxP3 (D6O8R) Rabbit Monoclonal Antibody (BSA and Azide Free)

Monoclonal Antibody for studying FOXP3. Validated for IHC,IHC,IF,F. Highly specific and rigorously validated in-house, FoxP3 (D6O8R) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #72338) is ready to ship. Product Usage Information This product is the carrier free version of product #12653. 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 # 12653 . 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 FoxP3 (D6O8R) Rabbit Monoclonal Antibody (BSA and Azide Free) recognizes endogenous levels of total FoxP3 protein. This antibody recognizes mouse FoxP3 protein and is also reactive with human FoxP3; however, this antibody is not suggested for immunohistochemical analysis of human tissues. Instead, FoxP3 (D2W8E) Rabbit Monoclonal Antibody #98377 is recommended for IHC analysis of human tissue samples. Species Reactivity: Mouse, Monkey Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro44 of mouse FoxP3 protein. Background Forkhead box (Fox) proteins are a family of evolutionarily conserved transcription factors containing a sequence known as Forkhead box or winged helix DNA binding domain (1). The human genome contains 43 Fox proteins that are divided into subfamilies. The FoxP subfamily has four members, FoxP1 - FoxP4, which are broadly expressed and play important roles in organ development, immune response, and cancer pathogenesis (2-4). The FoxP subfamily has several characteristics that are atypical among Fox proteins: their Forkhead domain is located at the carboxy-terminal region and they contain motifs that promote homo- and heterodimerization. FoxP proteins usually function as transcriptional repressors (4,5). FoxP3 is crucial for the development of T cells with regulatory properties (Treg) (6). Mutations in FoxP3 are associated with immune dysregulation, polyendocrinopathy, enteropathy, and X-linked syndrome (IPEX) (7), while overexpression in mice causes severe immunodeficiency (8). Research studies have shown that FoxP3 functions as a tumor suppressor in several types of cancer (9-11).
