Biotin-PEG4-amino-t-Bu-DADPS-C3-alykne is a PEG-based bioconjugation linker combining a biotin tag, a PEG4 spacer, a primary amino handle, a DADPS cleavable protecting group, and a terminal alkyne for copper-catalyzed azide-alkyne cycloaddition (CuAAC). It is designed for use in PROTAC assembly, affinity capture, and click-chemistry-based labeling workflows.

• Contains a terminal alkyne for CuAAC click chemistry.
• Includes a biotin moiety for affinity capture or detection.
• PEG4 spacer improves solubility and reduces steric hindrance.
• Primary amino handle enables amide coupling to carboxyl-containing partners.
• DADPS group provides acid-cleavable protection for controlled release.
• Stable as a powder when stored cold and protected from light.
