Our customer is looking for IFN gamma ELISA kit for bovine and guinea pig. His samples are serum and plasma. I have checked there's no product for bovine and guinea pig sample but, please check the product which has possibility to cross react.

Thank you for contacting us. We have the following products in our catalog: ab108863: Interferon gamma Human ELISA Kit We have tested the cross-reactivity with bovine samples and it is very low, around 1 %. We have never tested samples from guinea pig. ab100537: Interferon gamma Human ELISA Kit - 1 x 96 Well Plate ab100689: Interferon gamma Mouse ELISA Kit - 1 x 96 Well Plate Guinea pig IFN-gamma shares ~56% and ~41% to human and mouse respectively. Therefore this protein doesn’t seem to be that conserved between species and as these ELISA kits are sandwich-based and very species specific, I would expect minimal to zero cross reactivity with a guinea pig sample. The only way to know for sure would be to test and see. However, we might be able to add a bovine IFN-gamma ELISA Kit to our catalog. I will check and let you know. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
