| Hazard Information | Back Directory | [Description]
(2-pyridyldithio)-PEG2-t-butyl ester is a PEG linker which contains a pyridyl disulfide moiety and a t-butyl ester group. The pyridyl disulfide group can react with thiol groups of proteins over a wide range of pH level. The t-butyl ester group can be removed under acidic conditions. The hydrophilic PEG linker increases the water solubility of the compound. |
