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

Acid ceramidase is a lipid hydrolyase responsible for the degradation of ceramide into sphingosine and free fatty acids within lysosomes. It can also synthesize ceramide from sphingosine and free fatty acids as well. The reverse activity is pH dependent (6.0 vs 4.5, respectively). This suggests that the enzyme may have diverse functions within cells dependent on its subcellular location and the local pH. Recent studies have shown that acid ceramidase activity is aberrantly expressed in several human cancers and that it might be a useful drug target. As an example, inhibitors of enzyme activity have been shown to slow the growth of cancer cells alone or in combination with other established, anti-oncogenic treatments. Aberrant activity has also been shown in Alzheimer’s disease and overexpression may prevent insulin resistant (Type II) diabetes by free fatty acids.


Synthetic peptide derived from the C terminal region of the ASAH1 protein.
