I am planning to prepare coIP samples and use mass spec to get a protein
binding profile. By comparing control and mutant groups, I am hoping to
find targets that are more disease relevant. I use magnetic beads for Co-IP.
Now here comes the questions:
Would it be good enough to just use SDS buffer for elution? I know this is
the case if my next step is western blotting.
If not, would an acidic glycine buffer followed by a basic buffer (Tris-HCl
) be sufficient since this only results elution of native protein complexes?
What are the other methods you recommend for removing the SDS from protein
samples in addition to running them on a gel? Columns?
Thank you!!!!
