Cytochrome C western blot

[Victor Emelyanov]

Hi

Using Mab against cyt c (Santa-Cruz, 7H8 clone) in WBA of mitochondrial fractions, I always oserve only band of ca. 70 kDa and never innate protein of 15 kDa. Long ago, I saw the same using Pharmingen Mab. At that time I was said that cyt c forms covalently linked complex with some specific protein and that even relevant paper exists. Did you fix a problem? Indeed covalent complex? Or multimer? Now and then I didn't use chaotropic agent in Laemmli sample buffer (8M urea or Guanidine chloride). Maybe this is important? Don't hesitate to contact me.

Best,
