  • I have my protein complex in a buffer with very high salt concentration plus 5% glycerol. Is this buffer compatible with mass spectrometry?

What search engine do you use?

We use Mascot (Matrix Science) for protein identification. Protein inference, grouping and FDR (false discovery rate) estimation is performed in Proteome Discoverer and Scaffold.
