Product Information
| Description | SPDP-PEG2-NHS ester is a PEG-based PROTAC linker that has an amine-reactive N-hydroxysuccinimide (NHS) ester at one end and a sulfhydryl-reactive 2-pyridyldithiol group at the opposite end. This has a single molecular weight PEG spacer arm, which confers greater water solubility to the crosslinker and linked proteins compared to crosslinkers having only hydrocarbon spacers. |
| Synonyms | SPDP-dpeg(R)2-NHS ester; Opss-peg(2)-nhs; 2,5-dioxopyrrolidin-1-yl 2-ethoxy-3-(2-(3-(pyridin-2-yldisulfaneyl)propanamido)ethoxy)propanoate |
