Mal-amido-PEG4-NHS ester is a polyethylene glycol (PEG)-based bifunctional linker combining a maleimide group and an N-hydroxysuccinimide (NHS) ester. It is used in PROTAC synthesis and general bioconjugation to enable orthogonal coupling strategies: the maleimide reacts with thiols, while the NHS ester couples to amines. The short PEG4 spacer improves aqueous solubility and helps minimize steric hindrance during conjugation.
- Bifunctional maleimide and NHS ester for orthogonal conjugation
- PEG4 spacer increases solubility in aqueous media
- Enables thiol-selective and amine-selective coupling reactions
- Well-suited for PROTAC linker assembly and bioconjugation workflows
- Supplied with analytical documentation for research use

Medchemexpress LLC Mal-amido-PEG6-NHS ester | 1137109-21-7 | 98.8% | 601.60 | 500 MG
Mal-amido-PEG6-NHS ester is a PEG-based PROTAC linker used in the synthesis of PROTACs. PROTACs contain two different ligands connected by a linker: one for an E3 ubiquitin ligase and the other for the target protein. They exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
- PEG-based PROTAC linker
- Used in the synthesis of PROTACs
- Exploits intracellular ubiquitin-proteasome system
- Selectively degrades target proteins
Medchemexpress LLC (S,R,S)-AHPC-(C3-PEG)2-C6-Cl | 1835705-61-7 | MFCD31560481 | 99.9% | 749.44 g/mol | C39H61ClN4O6S | 1 G
(S,R,S)-AHPC-(C3-PEG)2-C6-Cl is a HaloPROTAC that couples the (S,R,S)-AHPC VHL ligand to a two-unit PEG linker and a C6-chloroalkyl HaloTag reactive group. It is used in cell-based assays to recruit the von Hippel-Lindau (VHL) E3 ligase and promote degradation of HaloTag fusion proteins.
- VHL ligand with PEG linker for E3 ligase recruitment.
- Induces degradation of HaloTag fusion proteins in cell assays.
- High purity for research applications (99.9%).
- Solid form, supplied as a 1 g laboratory package.
- Store at -80°C, protect from light, and store under inert gas.
