Description

Thermo Scientific Pierce PDPH is a short, pyridyldithiol-and-hydrazide crosslinker for reversibly conjugating sulfhydryls (cysteines) to carbonyls (aldehyde or ketones, such as those formed by oxidation of glycoprotein carbohydrates).

Features of PDPH :

Reactive groups: pyridyldisulfide and hydrazide
Reactive toward: sulfhydryl groups and carbonyl (aldehyde) groups
• Short (9.2A), sulfhydryl-to-aldehyde crosslinker with disulfide bond spacer arm (cleavable)
• Pyridyldithiol group results in attachment to sulfhydryls via disulfide bond, which can be cleaved with DTT, TCEP or other reducing agents
• 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
