Dear Histonetters! I was wondering if anyone out there is working with xenograft tumor models and knows of a good alpha smooth muscle actin antibody that will detect mouse tissue but would give minimal background in tumor cells??? I have tried 6 different ones, 3 from Biocare, 1 from Santa Cruz, and 2 from Abcam, but they all gave me very strong backgrounds. Any information would be greatly appreciated. Thank you.
