Many of Addgene’s recombinant antibodies encode sequences that were originally derived from hybridoma lines. In many cases, we provide results from assays performed with this hybridoma-derived antibody in addition to results from assays performed with the recombinant antibody. To prevent confusion, the application data represented on Addgene’s website clearly notes whether the hybridoma material or recombinant antibody material were used in the assay. In some cases, Recommended Applications are based on results from experiments performed with a hybridoma-derived antibody. If you have any trouble with the recombinant antibody for this same application please contact us at firstname.lastname@example.org.
