N-Boc-Biocytin is a Boc-protected biotin PEG linker containing a carboxylic acid and a Boc-protected primary amine. The carboxylic group reacts with primary amines to form stable, irreversible amide bonds, and the Boc group can be deprotected under acidic conditions to reveal a free amine for further conjugation. Supplied as a white to off-white solid with storage and shipping guidance for reagent stability.
- Provides a biotinylated PEG linker for conjugation chemistry.
- Forms stable amide bonds with primary amines.
- Boc protecting group allows controlled deprotection under acidic conditions.
- White to off-white solid suitable for biochemical assays.
- Stable when stored at recommended temperatures for extended shelf life.
