Antibodies for IVD Assay Development

R&D Systems, a Bio-Techne brand, has over 30 years of experience manufacturing highly trusted ELISA kits. The foundation of Bio-Techne’s immunoassays is R&D Systems antibodies, which offer breadth of target selection with reproducible results. R&D Systems antibodies are developed using industry-leading production and quality control specifications to ensure they are highly validated and specific, thus contributing to the unmatched performance of our immunoassays.

If you are pursuing the development of an in vitro diagnostic (IVD) assay on an existing or novel platform, our matched antibody pair catalog is the perfect starting point when you are depending on specificity and consistent supply.

Benefits of Using Our Matched Antibody Pairs for IVD Assay Development

  • Analyte specificity has been tested in a sandwich immunoassay using rigorously screened antibody pairs.
  • A paired detection antibody is recommend for each antibody designated as an ELISA capture antibody.
  • Bulk quantities of the antibodies are readily available.

Custom Monoclonal Antibody Panels for Novel Immunoassay Platforms

Bio-Techne offers more antibodies than what is listed in our catalog. For every monoclonal antibody listed in our retail catalog, we have up to 30 additional non-catalog antibodies also available. Screen these custom monoclonal antibody panels to find the antibody that will work for your novel immunoassay.

Our Custom Monoclonal Antibody Panels Provide:

  • Validated target specificity as all clones have been screened by direct ELISA for target detection.
  • A means to avoid full antibody development, thereby saving you time and money.
  • The ability to scale up production for bulk quantities of your antibody.
  • A consistent supply of the antibody for your long-term needs as it is produced in-house at Bio-Techne.
