SP-410-24kit Protea C4 LithTips Sample Prep Kit, 1-10 µL

The C4 LithTips Sample Prep Kits contain tips and reagents for reversed-phase solid phase extraction for protein sample clean-up and for spotting of medium and large-size proteins from samples for MALDI mass spectrometry. These kits are effective in concentrating and desalting small and large proteins, resulting in mass spectra with better S/ N and reduced salt adducts. The Sample Prep Kits contain C4 LithTips for 1-10 uL sample volumes, 10 mL Sample Reconstitution and Rinse solution, 10 mL Equilibration Solution, and 10 mL Elution Solution. The C4 monoliths are immobilized on the inner surface of a pipette tip, providing a large surface area for sample capture. In addition, the central portion of the monolith lining the tip is hollow, eliminating backpressure problems during pipetting.
