3-Fucosyllactose [41312-47-4]

3-Fucosyllactose (3-Fucosyl-D-lactose) is one of the major fucosylated oligosaccharides found in human breast milk. 3-Fucosyllactose shows prebiotic, immunomodulator, neonatal brain development, and antimicrobial function^[1].

3-Fucosyllactose (3-Fucosyl-D-lactose) (10 mg/mL) can inhibit the adhesion of enteric and respiratory pathogens to the human epithelial cell lines Caco-2 and A549^[2].

* Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
