Preparing the resin with a wetting solution (e.g., 50:50 acetonitrile in water).
Aspirating and dispensing the protein sample multiple times to maximize binding. Preparing the resin with a wetting solution (e
Using a high-organic solvent to release the purified protein directly onto a MALDI plate or into a fresh tube. Real-World Application: Mass Spectrometry Real-World Application: Mass Spectrometry While C18 is the
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: Contaminants like salts, buffers, and detergents can easily
Perfect for recovering larger proteins without losing them to the resin.
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?
Using these tips typically follows a simple four-step process:
