Q: We are interested in having a custom conjugation of saporin and our antibody. Do you remove unconjugated antibody from the final material you send us?
A: We do remove the unconjugated antibody and saporin from the final product that we send to you. And perhaps to answer a question you may not be asking, but may be curious about, the unconjugated material is not particularly usable, after it has been removed from the final product as it has been slightly modified in preparation for the conjugation.
