Thermo Scientific™ SM(PEG)12 (PEGylated, long-chain SMCC crosslinker), 1 g
Thermo Scientific Pierce SM(PEG)n is a series of amine-to-sulfhydryl crosslinkers that differ in length from 17.6 to 95.2 angstroms as a result of polyethylene glycol spacer arms containing n equals 2 to 24 ethylene glycol units.
Features
- Reactive groups: NHS ester and maleimide
- Reactive toward: amino and sulfhydryl groups
- Irreversibly crosslink proteins or peptides by flexible PEG spacer arms
- Polyethylene glycol spacer arms help maintain conjugate solubility
- Pure compound with defined structure and molecular weight, ensuring reproducible protein-modification effects
- PEG spacer provides unique advantages, including increased stability, reduced tendency toward aggregation and reduced immunogenicity
- Ideal for performing controlled, two-step protein conjugations (see Sulfo-SMCC)
