FAQs
What are small molecule haptens?
Small molecule haptens are low-molecular-weight compounds that, although non-immunogenic by themselves, can elicit an immune response when conjugated to larger carrier proteins, enabling the generation of specific antibodies against non-protein targets.
What is the difference between a hapten and an antibody?
A hapten is a small antigenic molecule that cannot trigger an immune response alone, while an antibody is a protein produced by the immune system that specifically recognizes and binds to antigens, including hapten-carrier complexes.
What is the function of the hapten?
The primary function of a hapten is to serve as a molecular target that, when attached to a carrier protein, stimulates the production of antibodies specific to its unique chemical structure for use in detection, quantification, or neutralization.
Can Creative Biolabs help design novel haptens for rare or custom targets?
Yes. Creative Biolabs specializes in rational hapten design tailored to the structural and electronic features of unique small molecules, including rare drugs, metabolites, pesticides, and toxins, ensuring optimal immunogenicity and antibody specificity.
