Thank you for contacting Abcam. I have looked over all the details that you provided and I would recommended that you increase you incubation of the primary antibody to an overnight incubation at 4C with gently agitation. If increasing the incubation time does not prove to be effective then please let me know. The antibody is covered under our Abpromise and so is guaranteed to work in western blot on human and mouse samples. If we cannot resolve this issue for you, then I would be happy. If there is anything else I can help with, please let me know.
