- Description
Biotin-PEG24-SPA is a biotinylation reagent with a biotin group and an NHS ester connected by a 24-unit PEG spacer. The PEG spacer improves aqueous solubility, supporting compatibility with biological workflows. The NHS ester reacts with lysine side chains and N-terminal amino groups at pH 7–9 to form stable amide bonds, making the reagent suitable for labeling proteins, peptides, and other biomolecules for use in affinity assays, pull-downs, and other biotin-streptavidin-based techniques.
