Our lab technicians have not tested anti-IL17C antibody A00164-2 on horse. You can run a BLAST between horse and the immunogen sequence of anti-IL17C antibody A00164-2 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 horse 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 horse quadriceps femoris in ELISA, you can get your next antibody for free.
