Does anti-Carboxypeptidase B2/CPB2 antibody PB9997 work on pig ELISA with liver?

W. Baker

Verified customer

Asked: 2015-08-17


Our lab technicians have not validated anti-Carboxypeptidase B2/CPB2 antibody PB9997 on pig. You can run a BLAST between pig and the immunogen sequence of anti-Carboxypeptidase B2/CPB2 antibody PB9997 to see if they may cross-react. If the sequence homology is close, then you can perform a pilot test. Keep in mind that since we have not validated pig samples, this use of the antibody is not covered by our guarantee. However we have an innovator award program that if you test this antibody and show it works in pig liver in ELISA, you can get your next antibody for free.
