Pierce™ SATA (N-succinimidyl S-acetylthioacetate) - FAQs

What is the best way to remove unreacted SATA (Cat. No. 26102) after peptide modification?

The best way for removing unreacted SATA (Cat. No 26102) would be HPLC. Another possibility would be to use desalting columns. In case the peptide is bigger than 1.8 kDa, you would like to use the Pierce Polyacrylamide Desalting Columns, 1.8K MWCO, 5 mL (Cat. No 43426).
