Thermo Scientific Pierce Sulfo-EGS is a water-soluble crosslinker that contains amine-reactive sulfo-NHS-ester ends around a 12-atom spacer arm, which can be cleaved by treatment with hydroxylamine at pH 8.5.

Features of Sulfo-EGS:

Reactive groups: sulfo-NHS ester (both ends)
Reactive towards: amino groups (primary amines)
• Water-soluble; compare to EGS
• Membrane-impermeable, allowing for cell surface labeling
• Crosslinks formed are reversible at pH 8.5 using hydroxylamine for 3 to 6 hours at 37°C
• Lactose dehydrogenase retained 60% of its activity after reversible crosslinking with EGS
