Overview
Product introduction：
Amine-PEG4-Desthiobiotin is a pegylated amine compound whose biotin-like group is elutable from streptavidin, making it ideal for carbodiimide (EDC) conjugation to carboxylates for labeling and purification.
Features of EZ-Link Amine-PEG4-Desthiobiotin, No-Weigh Format:
• Desthiobiotin—analog of biotin allows easy elution from streptavidin, an ideal feature for affinity purification applications
• Amine-activated—primary amine can be crosslinked to proteins and material surfaces using EDC and other crosslinkers
• Pegylated—polyethylene glycol (PEG) groups in spacer arm enhances water solubility of biotinylated molecules
This desthiobiotin compound is an amine-modified analog of biotin that contains a 4-unit polyethylene glycol (PEG) spacer arm. Desthiobiotinylation is accomplished by conjugating the primary amine to carboxyl groups on surface materials, peptides or proteins using the carbodiimide crosslinker . Carboxyl groups (-COOH) occur in aspartate or glutamate residues and the carboxy-terminus of polypeptides. When activated with NHS-ester Chemistry).
