C18zip -

Aspirate and dispense your peptide sample through the ZipTip.

Repeat using the same elution volume to ensure all peptides are recovered.

Dispense the liquid into a clean, sterile microcentrifuge tube. C18zip

Repeat . This prepares the resin to bind the peptides. 4. Sample Binding

In scientific research, are a common tool used for purifying and concentrating peptide samples before analysis. Because "C18Zip" is a laboratory product rather than a document title, "generating a full text" typically refers to the Standard Operating Procedure (SOP) for using them. Aspirate and dispense your peptide sample through the ZipTip

The sample is now ready for (MALDI-TOF or LC-MS/MS).

Repeat this cycle to maximize binding to the C18 media. Note: Slow, consistent pipetting is key for high recovery. 5. Washing (Desalting) Aspirate the Wash Solution (0.1% TFA). Dispense to waste. Repeat 3 times to remove salts, buffers, and detergents. 6. Elution Aspirate the Elution Solution (e.g., 60% ACN/0.1% TFA). Repeat

50–70% ACN in 0.1% TFA (depending on peptide hydrophobicity). 2. Wetting the Tip Set your pipette to 10 µL. Aspirate the Wetting Solution (100% ACN) into the tip. Dispense to waste. Repeat 2 times . This activates the C18 resin. 3. Equilibration Aspirate the Equilibration Solution (0.1% TFA). Dispense to waste.
