Monoclonal Antibody for studying PAX5. Validated for Western Blotting,Immunofluorescence (Immunocytochemistry),Flow Cytometry (Fixed/Permeabilized). Highly specific and rigorously validated in-house, PAX5 (D19F8) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #78966) is ready to ship. Product Usage Information This product is the carrier free version of product #8970. 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 # 8970 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 PAX5 (D19F8) Rabbit Monoclonal Antibody (BSA and Azide Free) recognizes endogenous levels of total PAX5 protein. Species Reactivity: Human, Mouse Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gln350 of human PAX5 protein. Background Paired box (PAX) proteins are a family of transcription factors that play important and diverse roles in animal development (1). Nine PAX proteins (PAX1-9) have been described in humans and other mammals. They are defined by the presence of an amino-terminal "paired" domain, consisting of two helix-turn-helix motifs, with DNA binding activity (2). PAX proteins are classified into four structurally distinct subgroups (I-IV) based on the absence or presence of a carboxy-terminal homeodomain and a central octapeptide region. Subgroup I (PAX1 and 9) contains the octapeptide but lacks the homeodomain; subgroup II (PAX2, 5, and 8) contains the octapeptide and a truncated homeodomain; subgroup III (PAX3 and 7) contains the octapeptide and a complete homeodomain; and subgroup IV (PAX4 and 6) contains a complete homeodomain but lacks the octapeptide region (2). PAX proteins play critically important roles in development by regulating transcriptional networks responsible for embryonic patterning and organogenesis (3); a subset of PAX proteins also maintain functional importance during postnatal development (4). Research studies have implicated genetic mutations that result in aberrant expression of PAX genes in a number of cancer subtypes (1-3), with members of subgroups II and III identified as potential mediators of tumor progression (2). PAX5, also known as B cell-specific activator protein (BSAP), was originally identified as a DNA-binding protein with affinity for both immunoglobulin heavy-chain and kappa light-chain loci (5). PAX5 is unique within the PAX family in being the only member with reported expression in the hematopoietic system. PAX5 is required to promote differentiation of common lymphoid progenitors (CLPs) into B cells (5,6); it is also required for the continued maintenance of B cell identity following differentiation (7). Disruptions to the expression of PAX5 have consequently been linked with lymphoid cancer development (8).
