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

Recognizes a ~102kDa identified as MSH2. Germline mutations in human mismatch repair genes (hMSH2, hMSH6, hMLH1, hPMS2) account for majority of the hereditary non-polyposis colorectal carcinoma (HPNCC). CpG dinucleotides in the hMSH2 and hMLH1 genes are hotspots for HNPCC mutations. These mutations cause a mismatch repair deficiency resulting in a mutator phenotype where the replication errors are not repaired. Microsatellites / simple repeatative sequences are prone to this type of replication errors and instability of these microsatellites correlates with the occurance of HPNCC. hMSH2 binds to another MutS homolog protein GTBP to form a heterodimeric complex called hMutSbeta, which binds to insertion/deletion loops in DNA.


Hybridoma produced by the fusion of splenocytes from BALB/c mice immunized with recombinant human MSH2 protein and mouse myeloma p3-NS1.Ag4-1 cells.
