PC-Biotin-PEG4-NHS carbonate is a PEG-based photocleavable biotinylation reagent bearing an NHS carbonate amine-reactive group. It is designed for use as a PROTAC linker or to introduce a light-cleavable biotin tag for biochemical conjugation, affinity capture, and downstream light-mediated release of labeled molecules.
- Photocleavable biotin enables light-controlled release of captured molecules.
- PEG4 spacer improves solubility and reduces steric hindrance in conjugates.
- NHS carbonate reacts with primary amines to form stable carbamate linkages.
- High reported purity supports use in synthesis and analytical workflows.
- Powder storage at -20°C and cold-solvent storage extend compound stability.
