Medchemexpress LLC Biotin-PEG2-C6-azide 50mg | 1011268-29-3 | 50 MG
Biotin-PEG2-C6-azide is a biotinylated PEG-based linker (CAS 1011268-29-3) containing an azide functional group used primarily in click chemistry and linker synthesis. It is supplied as a research reagent for conjugation, affinity capture, and PROTAC development.
- Contains a biotin tag for selective affinity capture of conjugates.
- Azide functional group enables copper-catalyzed azide-alkyne cycloaddition (click chemistry).
- PEG2 spacer improves solubility and provides flexible linkage between groups.
- Appropriate for PROTAC linker synthesis, bioconjugation, and pull-down assays.
- Provided in small laboratory pack sizes suitable for research use.
