- Mechanism of Action of DNP-BSA
DNP-BSA (2,4-dinitrophenyl-conjugated bovine serum albumin) is a classic hapten-carrier protein complex. As a small-molecule hapten, DNP (2,4-dinitrophenyl) alone cannot induce an immune response. However, when conjugated to the large carrier protein bovine serum albumin (BSA), it becomes a complete immunogen capable of efficiently activating the immune system and inducing the production of DNP-specific antibodies. AbMole’s DNP-BSA (2,4-Dinitrophenyl-Bovine Serum Albumin, M58157) serves as an important immunological tool with broad applications.
AbMole provides global researchers with high-purity, high-bioactivity inhibitors, cytokines, human monoclonal antibodies, natural products, fluorescent dyes, peptides, compound libraries, antibiotics, and other research reagents, widely cited in numerous publications and patents worldwide.
- As an Immunogen for Antibody Production
DNP-BSA (M58157, AbMole) is commonly used as an immunogen to generate DNP-specific antibodies in animals. By injecting DNP-BSA into animals, the immune system is activated, producing DNP-specific B and T lymphocytes, which subsequently secrete specific antibodies. These antibodies can be used in downstream immunological assays, such as detecting antigen-antibody reactions, and studying antibody specificity and affinity.
- As an Inducer for Allergic Reaction Models
DNP-BSA (2,4-dinitrophenyl-bovine serum albumin) (M58157, AbMole) is a commonly used allergic reaction antigen that can induce allergic responses and establish animal models of allergy. Sensitization can be achieved either by injecting DNP-BSA as an antigen to induce IgE antibody production or by directly injecting anti-DNP IgE antibodies. After a defined sensitization period, an antigen challenge is performed via intravenous injection of DNP-BSA to induce an allergic reaction. Allergic responses can be assessed by monitoring body temperature changes, measuring serum levels of inflammatory mediators, and observing mast cell degranulation and inflammatory cell infiltration in tissue sections.

- In Immune Tolerance Research
DNP-BSA (M58157, AbMole) can serve both as an immunogen to induce immune responses and as a tool to study mechanisms of immune tolerance. Administering DNP-BSA via different routes (e.g., subcutaneous, intraperitoneal, oral) can induce varying degrees of immune tolerance. Low doses of DNP-BSA administered orally or subcutaneously can induce immune tolerance, typically mediated by regulatory T cells (Tregs), which secrete inhibitory cytokines (e.g., IL-10 and TGF-β) to suppress effector T cell activation and proliferation. High doses of DNP-BSA administered intravenously can also induce immune tolerance, generally through clonal anergy, where T or B cells fail to be fully activated upon antigen stimulation, thereby preventing an effective immune response.
In 2014, two AbMole inhibitors were used in in vivo studies by the Spanish National Center for Cardiovascular Research (CNIC) and Columbia University, leading to publications in Nature and Nature Medicine.
