Cygnus Custom Development Services

Benefit from Cygnus’ knowledge in developing immunochemical reagents and methods for bioproduction impurities


Cygnus Technologies specializes in host cell protein (HCP) and DNA impurity detection. In addition to their catalog kits, they provide customized antibody and assay development services for HCP and DNA detection in recombinant biopharmaceuticals. Using their proprietary technologies, they generate and affinity purify sensitive and broadly reactive polyclonal antibodies. They have now successfully developed over fifty ELISAs for various recombinant expression systems, including bacteria, various yeasts, human and mammalian cell lines, as well as transgenic and plant expression systems.

Through their extensive networking with other high-quality special technology companies, they can integrate and manage projects requiring highly diverse technical inputs.
