Product Highlight

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:

  • ELISA
  • Flow Cytometry
  • Western Blot
  • Immunohistochemistry
  • Immunoprecipitation

Background

The reactivity of the antiserum is directed to the Fc and Fab subunits of both subclasses, IgG1 and IgG2. It includes a certain degree of reactivity with other immunoglobulins via the common Fab portion. In immunoelectrophoresis against goat serum a single characteristic precipitin line with a spur is usually obtained, representing primarily IgG2. If the IgG1 level in the sample approaches the concentration of IgG2, it may become visible as a second precipitin line. It does not react with any non-Ig protein in goat serum, as tested by immunoelectrophoresis and double radial immunodiffusion.

Product Source

Purified normal IgG isolated from pooled goat serum. Freund

Product Formulation

Purified hyperimmune donkey IgG lyophilized from a solution in phosphate buffered saline (PBS, pH 7.2). No preservative added, as it may interfere with the antibody activity. No foreign protein added.

Product Specificity

Inter-species cross-reactivity is a normal feature of antibodies to immunoglobulins, since Ig of different species frequently share antigenic determinants. Cross-reactivity of this antiserum has been tested in double radial immunodiffusion with the following results: bovine ++ guinea pig

Storage Conditions

The lyophilized IgG fraction is shipped at ambient temperature and may be stored at +4
