Thermo Scientific™ Sulfo-EGS (ethylene glycol bis(sulfosuccinimidyl succinate))
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
- 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
