Medchemexpress LLC Biotin-PEG2-C6-azide 5mg | 1011268-29-3 | 513.65 g·mol-1 | C22H39N7O5S | 5 MG
Biotin-PEG2-C6-azide is a biotinylated azide reagent used as a click-chemistry linker for bioconjugation, including PROTAC assembly, probe labeling, and affinity capture. The reagent features a biotin tag connected via a PEG2 spacer and a C6 alkyl spacer terminating in an azide for copper-catalyzed or strain-promoted azide-alkyne cycloaddition. Molecular formula C22H39N7O5S; molecular weight ≈ 513.65 g·mol-1.
- Provides a biotin handle for streptavidin/avidin affinity capture.
- Contains a PEG2 spacer to improve solubility and flexibility.
- Features a C6 linker terminating in an azide for efficient click chemistry conjugation.
- Suitable for PROTAC linker synthesis, probe labeling, and other bioconjugation workflows.
- Typically stored frozen to preserve reagent integrity (store at -20°C).
Medchemexpress LLC DSPE-PEG3-azide | 977.30 | 5 MG
DSPE-PEG3-azide is an azide-containing lipid suitable for forming micelles as nanoparticles for drug delivery. It functions as a click chemistry reagent, featuring an azide group that can participate in copper-catalyzed azide-alkyne cycloaddition (CuAAc) reactions with alkyne-containing molecules. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.
