KLH-Peptide Antigen

Why KLH-Peptide Conjugates are use as an antigen?

Keyhole Limpet Hemacyanin also called KLH, has minimal cross-species reactivity, therefore is the most commonly used carrier protein. KLH can be conjugated to small molecules of haptens or peptides for antibody production. Most peptides are not large enough in size to be immunogenic on their own. Conjugation of peptide to KLH is adequately large to be immunogenic. Contact Bio-Synthesis for Peptide-KLH Carrier Conjugation Services.
