Biotin-PEG7-Amine(CAT: I014221) is a versatile bioconjugation reagent used extensively in biochemical and molecular biology research. This compound features a biotin moiety for high-affinity binding to avidin or streptavidin, linked to an amine-functionalized polyethylene glycol (PEG) spacer with seven ethylene glycol units. The PEG7 spacer enhances solubility and reduces steric hindrance, facilitating efficient conjugation with biomolecules such as proteins, peptides, and nucleic acids. Biotin-PEG7-Amine is ideal for applications including protein labeling, assay development, and targeted delivery in drug discovery. Its high purity and stability ensure reliable and reproducible results, making it an essential tool for bioconjugation and molecular interaction studies.
