Pyrene-PEG5-biotin
This product is a high-purity heterobifunctional probe combining a hydrophobic pyrene fluorophore with a biotin affinity tag through a PEG5 spacer. The pyrene moiety enables strong fluorescence for sensitive detection and monitoring, while the biotin group binds with high affinity to avidin or streptavidin for immobilization, capture, or purification. The PEG5 spacer improves solubility, reduces steric hindrance, and enhances probe accessibility in both aqueous and organic systems.
