: The protein sample is aspirated through the tip, binding to the C4 resin.

This technology has been instrumental in recent studies, including identifying SARS-CoV-2 protease cleavage sites and characterizing human cannabinoid receptors. c4.zip

The C4 ZipTip is most commonly used in the workflow for (Matrix-Assisted Laser Desorption/Ionization Time-of-Flight). : The protein sample is aspirated through the

A C4 ZipTip is a standard pipette tip containing a microscopic bed of resin fixed at its distal end. Unlike C18 resins, which are used for smaller peptides, the C4 resin is optimized for larger, more hydrophobic molecules like proteins and large polypeptides. Primary Uses in Research Researchers use these tools for two main reasons: A C4 ZipTip is a standard pipette tip
