Thermo Scientific™ EMCH (N-ε-maleimidocaproic acid hydrazide)
Thermo Scientific Pierce EMCH is a mid-length, maleimide-and-hydrazide crosslinker for conjugating sulfhydryls (cysteines) to carbonyls (aldehyde or ketones, such as those formed by oxidation of glycoprotein carbohydrates).
Features
- Reactive groups: maleimide and hydrazide
- Reactive towards: sulfhydryl groups and carbonyl (aldehyde) groups
- Mid-length (11.8Å), sulfhydryl-to-aldehyde crosslinker with simple spacer arm (noncleavable)
- Maleimide group reacts with sulfhydryl groups to form stable thioether linkages
- Hydrazide group conjugates to oxidized sugars of glycoproteins and carbohydrates
- Use sodium meta-periodate to oxidize glycosylation (e.g., sialic acid) to reactive aldehyde groups
- Use with EDC to conjugate primary amine of hydrazide group to carboxyl groups
