Mouse anti-M13 phage coat protein g8p

Antibodies recognising M13 filamentous phage coat proteins are instrumental in the selection and detection of phages expressing specific antibody fragments or peptide sequences at their surface. The monoclonal antibodies manufactured and supplied by Exalpha react with either the pIII (g3p) or pVIII (g8p) proteins of M13 filamentous bacteriophage. All antibodies are available in a purified format. The antibodies are fully validated and are suitable for a wide range of techniques including:

  • ELISA
  • Flow Cytometry
  • Western Blot
  • Immunohistochemistry
  • Immunoprecipitation

Background

TCF 1 (T cell factor 1) is a member of the TCF/LEF (lymphoid enhancer factor) family of transcription factors. Members of this family along with β catenin, are involved in mediating Wnt signaling by transactivating downstream genes. TCF 1 is closely related to LEF-1, both of which are transcription factors expressed in mice during T cell differentiation. They regulate the T cell receptor α enhancer in transfections assays. TCF 1 becomes transcriptionally active through interaction with β catenin. Also, numerous splice variants of TCF 1 have been identified. Overexpression of TCF-1-specific splice forms appears to correlate with the metastatic behavior of colorectal cancer cells and with overproduction of lymphoid tyrosine protein kinase p56(lck).
