Our lab technicians have not tested anti-HARS/Hisrs antibody A05242 on monkey. You can run a BLAST between monkey and the immunogen sequence of anti-HARS/Hisrs antibody A05242 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 monkey 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 monkey brain in WB, you can get your next antibody for free.
