Carrier Protein
Carrier Protein — A protein to which a small peptide is conjugated to increase immunogenicity for antibody production, commonly BSA or KLH.
What Is a Carrier Protein?
A carrier protein is a larger immunogenic protein to which a small peptide hapten is conjugated to elicit an immune response. Peptides < 5 kDa are generally too small to be immunogenic alone and require conjugation to carriers such as BSA, KLH (keyhole limpet hemocyanin), or ovalbumin for antibody production.
Applications
- KLH: Preferred carrier for immunization (highly immunogenic). Peptide conjugated via Cys-maleimide or Glu-EDC chemistry
- BSA: Common carrier for screening and coating ELISA plates
- Tetanus toxoid: Carrier for human vaccine peptide conjugates (clinically proven safety)
