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:

  • Flow Cytometry
  • Western Blot
  • Immunohistochemistry
  • Immunoprecipitation

The importance of protein tyrosine phosphorylation in such diverse cellular processes as proliferation, differentiation and gap-juunction communication is reflected in the enormous number of protein tyrosine kinases that have been identified and described in the last thirty years. The roles played by anomalies in expression of these enzymes in cancer and other disease states has made them targets of intense research interest as part of the ongoing search for new therapies. Tyrosine kinases purified from mammalian tissue sources may be valuable to the study of generalized tyrosine phosphorylation or for the generation of specific phosphorylated peptides. Our PTK enzyme has been purified from porcine kidney utilizing both classical chromatographic procedures as well as affinity chromatography on immobilized substrate of random amino acid copolymers containing tyrosine, but not serine or threonine.
