Medchemexpress LLC DBCO-PEG12-maleimide | 00-00-0 | 98.0% | C52H74N4O17 | 10MG
DBCO-PEG12-maleimide is a PEG12-based bifunctional linker for bioconjugation and PROTAC synthesis. It combines a dibenzocyclooctyne (DBCO) moiety for strain-promoted alkyne-azide cycloaddition and a maleimide group for selective thiol conjugation, providing a flexible, hydrophilic spacer for assembling complex conjugates. Supplied as a high-purity reagent for research use.
- Enables copper-free click chemistry via strain-promoted alkyne-azide cycloaddition.
- Provides thiol-selective conjugation through a maleimide reactive handle.
- Offers a PEG12 spacer to increase solubility and reduce steric hindrance.
- High purity suitable for research applications.
- Stable when stored under recommended conditions.
Medchemexpress LLC Mal-PEG3-NHS ester | 1537892-36-6 | 99.5% | 398.36 g/mol | C17H22N2O9 | 100 MG
Mal-PEG3-NHS ester is a noncleavable antibody-drug conjugate (ADC) linker containing a maleimide group and an N-hydroxysuccinimide (NHS) ester separated by a three-unit polyethylene glycol (PEG3) spacer. It enables conjugation to thiols and primary amines for bioconjugation and ADC synthesis in research applications.
- Provides thiol and amine reactive groups for versatile bioconjugation.
- PEG3 spacer increases aqueous solubility and reduces aggregation.
- High purity suitable for research and conjugation workflows.
- Available in multiple pack sizes for small- to mid-scale synthesis.
- Store protected from light and under inert gas to maintain stability.
Medchemexpress LLC DSPE-PEG-biotin, MW 3400 | 98.4% | 3400 (average) | 250 MG
DSPE-PEG-Biotin, MW 3400 is a PEGylated phospholipid supplied as a white powder. The DSPE lipid tail anchors in membranes or liposomes while the PEG3400 spacer presents biotin for high-affinity capture, detection, or targeted delivery applications. The product is listed with an average molecular weight of 3400 and a reported purity of 98.43%.
- Provides biotin functional groups for streptavidin/avidin-based capture and detection.
- An amphiphilic structure that anchors efficiently into lipid bilayers and liposomes.
- PEG3400 spacer improves aqueous solubility and reduces nonspecific interactions.
- Available in multiple pack sizes for small- and preparative-scale work.
- Stable as a powder at -20°C; in-solution storage recommendations provided for longer-term stability.
