The C4 ZipTip is most commonly used in the workflow for (Matrix-Assisted Laser Desorption/Ionization Time-of-Flight). : Best for proteins > 10 kDa and highly hydrophobic peptides
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: which are used for smaller peptides
