Want to know the steps or techniques in purifying CYTOCHROME C. I just
want to know the steps or techniques, in this process. I am trying to
be precise. Since i am trying to find a UNKNOWN PROTEIN, i would like
to know the steps of this protein rather then buy one that has already
been put together. I want to learn the techniques and steps of this
protein.          Ted.

Hello, I am following up on your question about steps needed for the
purification of Cytochrome C. Here are some sites that describe the
process in detail.

I hope these are useful. Please let me know if I can be of further
assistance.  jdb-ga

Come on!! All you have to do is type ' "cytochrome c" purification '
into Google and you get your answer. Why would you be willing to spend
$40 for this?

I hope you understand that there is no one way to purify a protein.
There are dozens of different protein purification techniques, and
most methods use a combination of at least two of these, with the
conditions uniquely tailored. Knowing how to purify CytC will not help
you to purify anything else.
