Thank you for your inquiry.

For ab758, the immunogen that was used was cytoskeletal extract of human hepatocellular carcinoma cell line, Hep3B. We have not validated this antibody in pig. But the human sequence is 85% homologous with the pig cytokeratin 8 sequence. We generally say anything with >85% homology would be expected to cross-react, so this is right on the edge. However, we do have two anti-cytokeratin 8 antibodies that we know do work in pig as ab2531 and ab2530.

For ab27988, this antibody has been validated in pig and we therefore guarantee it will work for pig in IHC-P, IHC-Fr in accordance with our Abpromise.

For ab7504, the immunogen was human breast carcinoma cell line, MCF-7. Pig and human EpCAM is 83% homologous, so this is a little low. We have an anti-EpCAM that is predicted (>90% homology) to cross-react with pig, and that is ab71916. However, this hasn't been validated and therefore not guaranteed in pig.

I have to check with the lab on ab32362 and ab124687 since I don't have the immunogens readily available to BLAST.

For ab28028, full length native protein (purified): Vimentin isolated from bovine eye lens was used as an immunogen. Pig vimentin and bovine vimentin are 97% homologous, so there is a good chance this will cross-react with pig. However this hasn't been tested and therefore isn't validated in pig. We do have a few vimentin antibodies that work in pig though,like ab20346 and ab8069.

For ab11333, cultured human thymic fibroblasts was used as an immunogen. We don't have a particular protein sequence to look up for this one, so unfortunately we don't know how/if it will work with pig.

I hope this information helps. I'll be in touch again once I hear about ab32362 and ab124687.
