Medchemexpress LLC Biotin-PEG11-Mal | 1646619-56-8 | MFCD00017409 | 98.1% | C41H71N5O16S | 10MG
Biotin-PEG11-Mal is a bifunctional PEGylated linker that combines a biotin affinity tag with a maleimide reactive group for conjugation to thiol-containing biomolecules and for use in PROTAC synthesis. The PEG11 spacer provides flexibility and improved aqueous compatibility, enabling effective labeling, capture, or linkage in biochemical workflows.
- Biotin tag enables affinity purification and detection.
- Maleimide group reacts selectively with sulfhydryl (thiol) groups.
- PEG11 spacer improves solubility and reduces steric hindrance.
- High purity supports reproducible conjugation chemistry.
- Supplied as an oil in multiple pack sizes for experimental flexibility.
- Stable when stored under nitrogen at -20°C.
Medchemexpress LLC Apn-C3-peg4-azide | 2183440-32-4 | 98.6% | C24H32N6O6 | 10MG
APN-C3-PEG4-azide is a PEG-based heterobifunctional linker for PROTAC assembly and bioconjugation. It combines a thiol-reactive 3-arylpropiolonitrile (APN) group with a PEG4 spacer terminating in an azide, enabling selective cysteine modification and subsequent conjugation via copper-catalyzed or strain-promoted azide-alkyne cycloadditions.
- Thiol-reactive APN moiety enables selective cysteine conjugation.
- PEG4 spacer provides flexibility and water solubility.
- Terminal azide enables copper-catalyzed and strain-promoted click reactions.
- High purity suitable for synthetic and bioconjugation workflows.
- Available in multiple small-scale quantities for research use.
