BioLegend Covance Integration

The full catalog of over 1000 former Covance antibody products, including antibodies and research reagents for Neuroscience, Immunopathology (IVD IHC products), Cell Biology, Epitope Tags, and IHC Detection products, can now be found at


What’s changing?

  • All former Covance products have been assigned a new 6 digit BioLegend catalog number, but you will still be able to find products based on the previous Covance catalog numbers.

  • Orders should now be placed with BioLegend headquarters.  View BioLegend's current Ordering Instructions.

  • In May, the current site will be shut down and will no longer be available.

Key Improvements:

  • One website for all BioLegend products.

  • Place orders across both catalogs with one order. Simplifies the ordering and payment processes.

  • Improved search. Now, former Covance products can be searched by name, clone, catalog number, as well as alternate names. Search results can be filtered by categories.
