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

Mouse anti P53 (TP53 tumor suppressor protein)



Price (USD)



P53 is a tumor suppressor gene expressed in a wide variety of tissue types and is involved in regulating cell growth, replication, and apoptosis. It binds to MDM2, SV40 T antigen and human papilloma virus E6 protein. Alterations of the p53 tumor suppressor gene are considered critical events in multistage carcinogenesis of a wide range of human cancers. The mutations found in sporadic cancer are commonly missense mutations that inactivate the tumor suppressor activity of p53. These mutant proteins are much more stable than the normal p53 protein, frequently adopt an altered conformation and accumulate within the nucleus of the malignant cells. Mutations involving p53 are found in a wide variety of malignant tumors, including breast, ovarian, bladder, colon, lung, and melanoma. Positive nuclear staining with p53 antibodies has been reported to be a negative prognostic factor in amongst others breast carcinoma, lung carcinoma, colorectal, and urothelial carcinoma.
