NHS-LC-Biotin (NHS-X-Biotin)

NHS-LC-Biotin Product Description

NHS-LC-Biotin (NHS-X-Biotin) is a long chain amine reactive biotinylation reagent. NHS-LC-Biotin reacts efficiently and irreversibly with a wide range of compounds containing primary amine (-NH2) residues, including proteins, antibodies and other biomolecules.

NHS-LC-Biotin contains a biotin moeity, an elongated alkyl chain spacer arm and an active NHS ester. This biotinylation compound is membrane permeable, making it well suited for intracellular protein labeling. This compound should initially dissolved in a high quality, molecular biology grade, anhydrous solvent, such as DMSO (CovaChem 18252) or DMF (CovaChem 18251). Once reconstituted, this compound can be used in organic solvent, or amine free, near neutral buffer, such as PBS, pH 7.2 (CovaChem 19213).
