    Product Information

    Product Usage Information

    This product is the carrier free version of product #58935. 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 Na2HPO4, 3 mM KCl, 2 mM KH2PO4, and 140 mM NaCl (pH 7.8)). BSA and Azide Free.

    For standard formulation of this product see product #58935

    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

    TCPTP (TC45) (D7T7D) Rabbit Monoclonal Antibody (BSA and Azide Free) recognizes endogenous levels of total TCPTP (TC45) protein. This antibody does not recognize the 48 kDa (TC48) isoform.

    Species Reactivity:

    Human, Mouse, Rat, Hamster, Monkey

    The antigen sequence used to produce this antibody shares 100% sequence homology with the species listed here, but reactivity has not been tested or confirmed to work by CST. Use of this product with these species is not covered under our Product Performance Guarantee.

    Species predicted to react based on 100% sequence homology:

    Bovine, Dog, Pig

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro382 of human TCPTP (TC45) protein.

    Background

    T cell protein tyrosine phosphatase (TCPTP, PTPN2, PTN2) is a non-receptor protein tyrosine phosphatase (PTP) that regulates signal transduction pathways by catalyzing the dephosphorylation of tyrosine residues (1). Two described TCPTP splice variants include a 48 kDa isoform (TC48) that is targeted to secretory pathway organelles (e.g., endoplasmic reticulum) by a hydrophobic carboxy terminus, and a 45 kDa isoform (TC45) that actively shuttles between the nucleus and cytoplasm (2). TCPTP substrates include receptor and non-receptor tyrosine kinases, such as EGFR, JAK1/3, and Src-family kinases, as well as STAT3 and other nuclear substrates (3-6). Research studies show that the corresponding PTPN2 gene is deleted in a subset of human T-cell acute lymphoblastic leukemias. The loss of TCPTP has been suggested to promote tumor progression through enhanced JAK/STAT signaling (7,8).

    Alternate Names

    protein tyrosine phosphatase non-receptor type 2; protein tyrosine phosphatase, non-receptor type 2; PTN2; PTPN2; PTPN2 iso2; PTPT; T-cell protein tyrosine phosphatase; T-cell protein-tyrosine phosphatase; TC-PTP; TCELLPTP; TCPTP; Tyrosine-protein phosphatase non-receptor type 2
