By definition, an antibody is a protein produced by the body’s immune system when it detects harmful substances, called antigens such as microorganisms (bacteria, fungi, parasites, and viruses) and chemicals.

In instances where access to a target protein is unavailable, but the amino acid sequence is known, peptide antigens offer an intelligent solution for antibody generation. Peptide antigens are being used increasingly so because they have several advantages such as low probability of cross-reactivity, greater flexibility in antigen selection, ease of synthesis and low cost as well as efficacy.
