生物活性	Polyethylene glycol 12-hydroxystearate, a Macrogol 15 hydroxy stearate, is a permeability enhancer^[1].
体外研究 (In Vitro)	Polyethylene glycol 12-hydroxystearate is used to increase the aqueous solubility of Biopharmaceutical Classification System (BCS) Class 2 and 4 lipophilic molecules. Polyethylene glycol 12-hydroxystearate has shown an enhancement in permeability of medium sized biological drugs across epithelia^[1].

Cell Assay ^[1]	For both MTS and LDH cell viability assays, cells are seeded at a density of 1×10⁴ cells on 96-well plates and cultured for a minimum of 24 h. Solutol HS-15 (in 25 mM HBSS:HEPES, pH 7.4) solutions are applied at concentrations above and below the critical micelle concentration (CMC) (0.01 mM to 20 mM) and cytotoxicity is determined using the MTS and LDH assays. 25 mM HBSS:HEPES is used as a negative control and Triton-X 100 (3 mM) as a positive control. Following 3 h incubation, the MTS reagent in media and LDH working solution are added to the cells and the cells are incubated for a further 3 h at 37°C^[1]. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
