We are currently using anti-Cullin 4B/CUL4B antibody PA1233 for mouse tissue, and we are satisfied with the WB results. The species of reactivity given in the datasheet says human, mouse, rat, zebrafish. Is it true that the antibody can work on goat tissues as well?

Verified customer

Asked: 2019-04-29


The anti-Cullin 4B/CUL4B antibody (PA1233) has not been tested for cross reactivity specifically with goat tissues, but there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in goat you can get your next antibody for free. Please contact me if I can help you with anything.
