NJ Bio

NJ Bio is a private contract research, development, and manufacturing organization focused on integrated chemistry and biology services for biotech and pharmaceutical clients. The company is best known for expertise in antibody-drug conjugates, bioconjugation, payload-linker chemistry, oligonucleotides, mRNA, protein degraders, analytical testing, and GMP manufacturing support. NJ Bio operates from Princeton, New Jersey, with additional chemistry operations in Bristol, Pennsylvania and Mumbai, India. Rather than advancing a proprietary therapeutic pipeline, it provides fee-for-service discovery, development, translational research, and early clinical manufacturing capabilities. The company has positioned itself as a specialist partner for complex conjugates and advanced therapeutics, particularly ADCs and related bioconjugates.
