Elution of Tryptic Peptides

Processing time Step Comments / Tips
45–60 minutes Centrifuge filtration units for 15 minutes at 12,000 × g to elute peptides. To maximize tryptic peptide recovery, increase the centrifugation speed to 12,500 × g or 13,000 × g if need be to pass all the digest solution through the filter.
Add 15.8 μL 50 mM ABC to elute any remaining peptides on filter. Centrifuge for 15 min at 12,000 × g.
