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

Catenins are proteins that connect cadherin/β-catenin cell adhesion complexes to the actin cytoskeleton. Although originally discovered in testis, αT-catenin is expressed in other tissues, the highest levels being observed in heart. Immunohistochemical analysis showed human αTcatenin localization at intercalated discs of cardiomyocytes and in peritubular myoid cells of testis. It is proven that αT-catenin can functionally restore cell-cell adhesion in colon cancer cells lacking α-catenins. This indicates that this protein is involved in the formation of specific cell-cell contacts in specific types of muscle cells. The encoded protein has about the same predicted size (100 kDa) as other α-catenins to which it shows an overall amino acid identity of 57%. In cells transfected with αT-catenin cDNA, interaction with β-catenin was demonstrated by coimmunoprecipitation. This antibody is specific for αT-catenin and does not cross react with αE-catenin or αN-catenin by Western blot.


Hybridoma produced by the fusion of splenocytes from C57BI/6 mice immunized with a synthetic peptide derived from the human αT-catenin protein and SP2/0-Ag14 mouse myeloma cells.
