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

Sulf-2 exhibits arylsulfatase activity and highly specific endoglucosamine-6-sulfatase activity. It can remove sulfate from the C-6 position of glucosamine within specific subregions of intact heparin. Mammalian Sulfs are endoproteolytically processed and secreted into the extracellular space of transfected cells, where they exhibit both arylsulfatase activity and highly specific endoglucosamine-6-sulfatase activity against intact heparin. Though the molecular weight of full length human Sulf2 is 100455 Da (870 amino acids), the endogenous Sulf2 is found by western blot to be present at molecular weights of 24.4, 33.7 and 51-60 kDa. Higher molecular weight species may be found depending on tissue and/or cell type. Analysis of human tumor tissue and tumor cell lines suggests that HSulf-1 is misregulated in cancers. HSulf-1 is found in a variety of normal tissues but is down-regulated in tumor cell lines originating from ovarian, breast, pancreatic, renal, and hepatocellular carcinoma. Tumors formed by cells expressing Sulf demonstrate enhanced extracellular matrix deposition. The 6-O-sulfation of heparan sulfate of myeloma tumor cells may be a critical factor in determiningand regulating the in vivo growth of this cancer.
