C4zip [ESSENTIAL - Hacks]

Aspirating and dispensing the protein sample multiple times to maximize binding.

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? Aspirating and dispensing the protein sample multiple times

Perfect for recovering larger proteins without losing them to the resin. Aspirating and dispensing the protein sample multiple times

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

Essential when working with low-abundance samples.

Using these tips typically follows a simple four-step process:
