Protein Modification Reagents
Thermo Scientific™ Pierce™ HRV 3C Protease Solution Kit (2 units/μL)
Remove fusion tags from proteins with the HRV 3C cleavage sequence with this recombinant cysteine protease that is dual tagged for easy removal from the sample after cleavage.
Thermo Scientific™ WELQut Protease (5 U/μL)
Thermo Scientific™ WELQut Protease is a highly specific serine protease cleaving outside the WELQX recognition motif to remove N-terminal protein fusion tags.
Thermo Scientific™ Pierce™ Cysteine-HCl
Make sulfhydryl assay standards or perform protein refolding experiments using this pure, crystalline cysteine hydrochloride (Cys-HCl).
Thermo Scientific™ Pierce™ Hydroxylamine-HCl
NH2OH (CAS 7803-49-8) to cleave Asn-Gly peptide bonds or deprotect sulfhydryls following S-acetylthioacetate modification with SATA reagent.
Thermo Scientific™ Pierce™ Sulfo-NHS-Acetate
Amine-reactive (NHS ester) compound to permanently block primary amines (e.g., protein lysine side chains) to prevent interactions or later conjugation.
