Hi Peter, you need to input the name (or parts of the name) of your epitope into multiple antibody search engines, like this one:

http://www.linscottsdirectory.com/search/antibodies/searchStr:Lewis%20X%20epitope/searchMode:specificity/hostId:/reactiveId:/applicationId:/formatId:/antibodyTypeId:/isoTypeId:/pageSize:100

If problems persist, please consider having a custom antibody made against the relevant peptide. We can offer such service for goat antibodies (high yield, low costs).

See http://everestbiotech.com/custom-antibody-services/

There are other cost-effective solutions if you don't need a lot of antibody (for example custom rabbit services with very short waiting times).

copy & paste "6-sulfo-sialyl Lewis X epitope" into google. The first 2 hits directly mention MECA-79, a mAb to sulfated core-1 O-glycans.
