Protein Labeling Reagents
Thermo Scientific™ EZ-Link™ Maleimide Protein Labeling Kit
A convenient method to label proteins with varying amounts of maleimide for crosslinking or conjugation with a thiol/sulfhydryl containing moiety. Sulfo-SMCC reacts with primary amines on a protein to form a covalently attached maleimide group that can be further reacted with a thiol/free cystine.
Cytiva Amersham™ QuickStain Protein Labeling Kit
Amersham QuickStain enables protein detection directly after SDS-PAGE or transfer. Supports Western blot normalization for quantitative Western blotting.
