Peptide Antibody Services for Antibody Generation

About Peptide Antibody Services

Immunizing with a peptide corresponding to a specific region of a protein antigen is a popular method to develop custom antibodies. With this strategy, you only need the amino acid sequence of a predicted/selected epitope within the protein antigen, avoiding homologous regions to minimize cross reactivity with other proteins. Antigenic peptides of 10-20 amino acids in length provide optimal epitope diversity while still offering superior specificity compared to immunizing with the full length protein sequence. The peptide is usually conjugated to a carrier protein such as KLH or BSA to enhance stimulation of an immune response. Antibodies are generated against the peptide sequence and the carrier protein. Therefore, the highly specific antibodies directed against the peptide are separated by affinity purification.

Why Use Peptide Antigens for Immunization?

  • Peptide epitopes represent antigen proteins
  • Chemical synthesis yields defined epitopes
  • Lower probability of cross-reactivity
  • More flexibility in antigen selection
  • Sequence diversity and PTMs can be addressed
  • Easy to synthesize, cost-effective and stable

Application Notes for Antibody Services (copy 1)

"The RV 144 HIV trial is considered as one of first successful HIV vaccine trials. It has become clear that the V2 loop of gp120 is an important site for immunogenicity and protection from HIV infection. The use of JPT’s PepStar™ microarray technology has been very useful for the correlation of the clinical outcome with humoral immune responses. As have the cyclic peptides been from JPT to validate these findings!"
J. Currier, PhD (Walter Reed Army Institute, Rockville, Maryland, USA)
