Introduction to Nitrofurans
Nitrofurans are a class of drugs that have been used as antibiotics for preventing and treating bacterial infections in a number of livestock species. Pilot studies have shown that nitrofurans are usually composed of a structure of 5-nitrofuran ring and have a broad range of bactericidal effects. Many kinds of nitrofurans, such as nitrofurazone (NFZ), nitrofurantoin (NFT), and furazolidone (FZD), have been developed and widely used in animal food production. Moreover, a variety of metabolites of nitrofurans, including 3-amino-2-oxazolidinone (AOZ), semicarbazide (SEM), as well as 3-amino-5-morpholinomethyl (AMOZ) have been identified and have become significant biomarkers for detecting illegal use of nitrofurans in foods.
In addition, various immunoassays have also been generated to provide a fast, reliable and high-throughput screening system for the risk assessment of animal food. Among them, the small molecule antibody has been considered as a powerful tool for detecting nitrofurans and their metabolites. Normally, antibodies against different haptens for nitrofurans metabolites are designed based on the specific binding of new haptens and a carrier protein. Different species of animals, such as rats, mice, rabbits, goats, and pigs, can be immunized for synthesizing immunogens. Furthermore, recent researchers have revealed that many kinds of nitrofuran-based hapten derivatives can also be conjugated to target proteins for producing small molecule antibody with high specificity. The data have suggested that the sensitivity of different antibodies varies significantly, but in general, they all have very high sensitivity and no or litter cross-reactivity (<0.01) with the carrier protein or other metabolites.

Our Platform for Nitrofurans Hapten Design and Synthesis
In the past few years, nitrofuran drugs have been prohibited by many countries due to their potential carcinogenicity and mutagenicity in humans. However, these drugs could be illegally used in animal feeds. Therefore, many small-molecule antibodies have been developed for detecting the presence of nitrofurans and the metabolites in food-producing animals. Creative Biolabs has established a one-stop solution platform to design, synthesize, and modify nitrofuran-associated haptens for further antibody production. Currently, a large number of haptens for the main types of nitrofuran metabolites, including but not limited to: the haptens for AOZ, the haptens for SEM, and the haptens for AMOZ, have been designed for developing antibodies for a broad-spectrum test. In addition, we also offer a wide range of small molecule antibody discovery services for our clients by using the hybridoma technique and novel haptens, which can be used to precisely detect the metabolites of nitrofuran antibiotics.
