Thermo Scientific™ Pierce™ SAT(PEG)4 (PEGylated N-succinimidyl S-acetylthioacetate)
Thermo Scientific Pierce SAT(PEG)4 is a long-arm (18.2 angstroms), pegylated form of SATA, a sulfhydryl-addition reagent for covalent modification of primary amines to facilitate controlled, heterobifunctional crosslinking.
Features
- Thiolate and PEGylate primary amines in one step
- Add sulfhydryl groups for heterobifunctional crosslinking without compromising protein solubility
- NHS-activated for efficient PEGylation of primary amines at pH 7-9; reaction of NHS-ester group results in formation of stable, irreversible amide bonds
- 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
