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

Akt is a general protein kinase capable of phosphorylating several known proteins including TBC1D4 (TBC1 domain family, member 4). Akt signals downstream of phosphatidylinositol 3-kinase (PI(3)K) to mediate the effects of various growth factors such as platelet-derived growth factor (PDGF), epidermal growth factor (EGF), insulin and insulin-like growth factor I (IGF-I). Plays a role in glucose transport by mediating insulin-induced translocation of the GLUT4 glucose transporter to the cell surface. Mediates the antiapoptotic effects of IGF-I. Mediates insulin-stimulated protein synthesis, partly by playing a role in both insulin-induced phosphorylation of 4E-BP1 and in insulin-induced activation of p70 S6 kinase. One of the essential functions of Akt is the regulation of glycogen synthesis through phosphorylation and inactivation of GSK-3α and β (Promotes glycogen synthesis by mediating the insulin-induced activation of glycogen synthase). In addition to its role in survival and glycogen synthesis, Akt is involved in cell cycle regulation by preventing GSK-3β mediated phosphorylation and degradation of cyclin D1. Catalytic activity: ATP + a protein = ADP + a phosphoprotein.
