A method of stimulating an immune response with a hapten immobilized on a nitrocellulose membrane.

Abstract

Hapten refers to a chemical compound of small molar mass (typically less than 1000 daltons) that can bind with an antibody, but cannot initiate an immune response by itself unless it is conjugated to a protein carrier of larger molar mass. A novel method to prepare a hapten to generate anti-hapten immunity without covalent conjugation to a carrier was developed. Coating both water-soluble and -insoluble haptens onto a nitrocellulose membrane effectively presented haptens to the system and caused the generation of specific anti-hapten B lymphocytes and antibodies by immunization both in vitro and in vivo. This method has a potential to substitute for conventional hapten carrier conjugation to generate anti-hapten immunity.
