Perfect for recovering larger proteins without losing them to the resin.
While C18 is the "gold standard" for peptide mapping, it can bind proteins so tightly that they become nearly impossible to elute. The shorter carbon chain of the C4 resin offers:
Aspirating and dispensing the protein sample multiple times to maximize binding.
Rinsing with a buffer like 0.1% trifluoroacetic acid (TFA).
In recent patent filings and research papers, C4 Zip-tips have been critical for identifying protein isoforms and calculating theoretical masses within 0.5 Da of their primary amino acid sequences. By removing buffers and exchange salts, researchers can achieve the high-resolution mass spectra required for modern drug development and biological research. CN101883788A - 多肽，抗体可变结构域&拮抗剂
In the world of proteomics, the quality of your mass spectrometry data is only as good as your sample preparation. Contaminants like salts, buffers, and detergents can easily drown out the signals of the very proteins you’re trying to study. This is where become indispensable. What are C4 Zip-tips?
