Medchemexpress LLC M-PEG12-NHS ester | 2207596-93-6 | ≥98.0% | C30H55NO16 | 500 MG
m-PEG12-NHS ester is a PEG-based PROTAC linker designed for the synthesis of PROTACs. PROTACs utilize the intracellular ubiquitin-proteasome system to selectively degrade target proteins by connecting a ligand for an E3 ubiquitin ligase and a ligand for the target protein via a linker.
- PEG-based PROTAC linker
- Used in the synthesis of PROTACs
- Exploits ubiquitin-proteasome system to degrade target proteins

Medchemexpress LLC Biotin-PEG4-dialkoxydiphenylsilane-picolyl azide | 2599839-59-3 | MFCD00137487 | 95.0% | C47H67N9O10SSi | 10MG
A clickable, acid-cleavable biotinylated PEG4 azide designed as an enrichment handle for labeling and enriching cell-surface glycoproteins. It incorporates a picolyl azide for efficient bioorthogonal conjugation and a dialkoxydiphenylsilane linker that permits acid-triggered release following affinity capture, providing a workflow for selective labeling, capture, and release of target biomolecules.
- Enables copper-catalyzed azide-alkyne cycloaddition (CuAAC) for covalent labeling.
- Compatible with strain-promoted alkyne-azide cycloaddition (SPAAC) for copper-free reactions.
- Acid-cleavable dialkoxydiphenylsilane linker allows release after enrichment.
- PEG4 spacer improves solubility and reduces steric hindrance.
- Biotin enables strong affinity capture with streptavidin reagents.
- Supplied with typical purity of 95% for consistent labeling results.
