• Consistent quality and performance over time

Available Engineering Services

• Modification of the species, isotype, hinge, and Fc region
• Generation of active truncated forms
• Improved yield without any change in affinity

The Process

1. Customer provides:
   a) Cell line expressing antibody or full-length antibody sequence.
   b) Antigen for testing the recombinant antibody using direct ELISA.
   c) Small aliquot of purified antibody.

2. Conversion, small scale expression of recombinant antibody, and comparison to the original hybridoma-derived antibody by R&D Systems.

3. Provision of data report and sample for customer's evaluation.

4. Exclusive supply of purified antibody.

5. Sequence and cell line(s) placed with third party for storage and security.

Panels of Non-Catalog Antibodies.

For every monoclonal antibody in our catalog, we have a panel of non-catalog antibodies available.
You can test these antibody panels in your application to find the antibody that produces optimal results.

Screen Antibody Panels to Identify Antibody Matched Pairs

The antibody matched pair you are looking for could be hiding in our selection of antibody panels.
Maximize your chances of successful antibody pairing by ordering our available antibody panels.

Consistent Antibody Supply

• Each antibody panel is produced in-house at R&D Systems, so we can meet your long-term supply needs.
• No 3rd party suppliers, which means no additional supply/licensing complications.
• All antibody panels are positive in direct ELISA for the analyte of interest.
• Convert any of our monoclonal antibodies to recombinant antibodies, and immortalize your antibody supply.
• Explore other antibody projects: antibody engineering, conjugation services, and more.
