5% PITC IN N-HEPTANE 40ML EACH，400208，Applied Biosystems

5% PITC (phenylisothiocynate) in heptane is used for N-terminal protein sequencing applications. PITC is a derivatization reagent used to tag amino acids in the protein sequencer and amino acid analyzer. An optimal PITC concentration is required to ensure efficient amino acid coupling with minimal background contribution from excess reagent. This reagent is used in conjunction with other protein sequencing reagents.
