Product Information

Description	SPDP-PEG6-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	2,5-dioxopyrrolidin-1-yl 3-oxo-1-(pyridin-2-yldisulfanyl)-7,10,13,16,19,22-hexaoxa-4-azapentacosan-25-oate; SPDP-dpeg(R)6-NHS ester; Opss-peg(6)-nhs
IUPAC Name	(2,5-dioxopyrrolidin-1-yl) 3-[2-[2-[2-[2-[2-[2-[3-(pyridin-2-yldisulfanyl)propanoylamino]ethoxy]ethoxy]ethoxy]ethoxy]ethoxy]ethoxy]propanoate
