Yes I am looking for cytochrome c release in human breast cancer cells. I would recommend you to go for Santa Cruz antibodies for the same. They are quite good. Happy research :)
Thanks a lot Lisa Saxena, Dilruba Ahmed and L. Miguel Martins! I will be trying with western blotting at first but I am truly gratefull for other ideas and tips (which can be really important if WB will not work) :)
