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

Calreticulin, a Ca2+ chaperone, is an abundant highly conserved calcium binding protein found in the lumen of the endoplasmic reticulum of eukaryotic cells. This lumen protein can be used to measure the intactness of membrane preparations. It is used as a marker for subcellular fractionation of cells.


Recombinant protein derived from the carboxy terminus of the calreticulin protein fused to KLH.

Positive Control

MDCK cells; MCF-7 cells. Suitable for use against recombinant proteins conjugated to OVA, GST, His tags and other.


Provided as solution in phosphate buffered saline with 0.08% sodium azide
