Hapten protein complex
WebDec 20, 2024 · 6. The hapten/prohapten model. The hapten model is based on the binding of small chemicals to proteins or peptides and thus generating new antigenic determinants. These complexes are processed by APCs in lymphoid tissues and generate antigenic hapten-peptides that have the ability to stimulate T-cells in an HLA dependent manner. WebThe carrier protein, because it is large and complex, confers immunogenicity to the conjugated hapten, resulting in antibodies being produced against epitopes on the hapten and carrier. Many proteins can be used as carriers and are chosen based on immunogenicity, solubility, and availability of useful functional groups through which …
