Protein Modification Reagents
Thermo Scientific™ Trypsin, TPCK Treated
Thermo Scientific Pierce TPCK Trypsin is a serine endoprotease that is applicable to amino acid analysis and protein sequencing, mapping and structural studies; the immobilized form allows sample separation after treatment.
Thermo Scientific™ Pierce™ SATA (N-succinimidyl S-acetylthioacetate)
Short (2.8A), amine-reactive (NHS ester) sulfhydryl-addition reagent; creates stable (protected yet exposable) -SH group for protein crosslinking strategies.
