Anti-small molecule hapten antibodies enable the detection of small molecules using robust and rapid immune detection technologies, such as ELISA, LFIA and IHC/IF. Either raised against endogenous small molecules (amino acid metabolites, lipids, saccharids, nucleotides, steroids, ...) or exogenous compounds (drug and pesticide residues, chemical pollutants,...), anti-hapten antibodies constitute attractive detection tools not only in the field of human health, for diagnostic and therapeutic applications, but also in areas such as food safety and environmental monitoring.
Combining 15 years of experience in the development of small molecule antibodies, Creative Diagnostics holds a specific expertise in the design of small molecule / protein carrier adducts. Based on our capacities in antigen design, we developed high quality small molecular monoclonal antibodies against a variety of targets.
Our advantages of custom small molecule mAbs services
A personalized strategy for antigen design, based on an in-depth analysis of the physico-chemical properties, immunogenicity and potential competitors of the small molecule target to address, and tailored to the client's intended use of the antibody. Read More
For antibody production, the hapten must contain active groups such as hydroxyl, carboxyl, amino etc. Theoretically the small molecules can be directly coupled with the carrier protein, but sometimes the small molecules with simple structures cannot be recognized by the immune system. Adding a certain length of the interval arm to the proton protrusions on the surface of the carrier protein will significantly improve the immune efficiency, thereby increasing the chances of producing antibodies against hapten. When conjugating a small molecule with complex structure, it is not necessary to add a spacer arm.
Quality controls, 24 hours services, Go/No-Go decisions points at the end of each phase, for transparent projects with limited risk and reasonable costs.
Full ownership of the antibody-producing clone is granted to the client at the end of the study, together with at least 3mg of purified monoclonal immunoglobulin.
