Biotin-PEG2-amine is a biotinylated compound featuring a flexible polyethylene glycol (PEG) spacer linked to a terminal amine. The PEG2 segment enhances solubility and reduces steric hindrance, facilitating efficient bioconjugation in aqueous environments. This molecule is widely utilized in research for labeling, immobilization, and affinity purification applications, particularly in the development of biosensors and targeted delivery systems. Its amine functionality enables easy covalent attachment to a broad range of biomolecules, supporting advanced studies in proteomics, diagnostics, and molecular biology.
