Thermo Scientific™ Pierce™ Controlled Protein-Protein Crosslinking Kit

Chemically conjugate any two purified proteins (antibodies, enzymes, carriers, etc.) using sulfo-SMCC crosslinker, a complete kit with modification reagents and buffers.

2

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.

3

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.

4

Thermo Scientific™ HABA (4'-hydroxyazobenzene-2-carboxylic acid)

A colored, biotin assay reagent HABA (4'-hydroxyazobenzene-2-carboxylic acid) to measure biotinylation levels of biotinylated antibodies or proteins.
