| Description | Biotin-PEG-Alk (MW 1000) is a biotinylated polyethylene glycol (PEG) derivative with alkyne functionality for click chemistry applications. Biotin serves as an enzyme co-factor suitable for protein labeling, while PEG provides hydrophilic, water-soluble, and low-toxicity characteristics. The alkyne group (Alk) facilitates copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions with azido-modified molecules, enhancing the compound's ability to target and bind with biotin receptors. |
