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

Sphingolipids have emerged as central signaling molecules regulating a variety of fundamental cell responses such as cell death and differentiation, proliferation and inflammation. Ceramide has been a main focus of research since it possesses pro-apoptotic capacity in many cell types. Sphingosine-1-phosphate (S1P), which is generated from ceramide by the actions of ceramidase and sphingosine kinase can potently induce cell proliferation via binding to and activation of the S1P family of receptors. The balance between ceramide and sphingosine-1-phosphate determines whether cells undergo apoptosis or proliferate, two cell responses that are critically involved in tumor development. The amino acid sequence for sphingosine kionase 1a differs from sphingosine kinase 1 only in the absence of a valine at position 4 of sphingosine kinase 1a.
