Antibody modification & bioconjugation service


Antibodies and antibody based reagents have been imperative biological tools to identify targeted molecular species, including proteins, peptides, virus and many small molecules. In recent years, many therapeutic antibodies have been developed as effective bio-drugs. Surface modified and bio-conjugated of antibodies have been found tremendous applications for ehanced stability, sensitivity and additional functionalities in their use as diagnostics and therapeutics.

Nanocs has been a long time expert in the field of site specific bio-modification and conjugation for antibody and antibody fragments. During the past decade, we have developed a handful reagent for various functional group for antibody modifications. A number of bioconjugation reagents, including fluorophores, enzymes, biotins, PEG derivations, are readily available from our conjugation reagent tool pools.
