L-histidine completely inhibits growth and its effect on viability is inversely related to FLO11 expression. L-histidine does not affect the viability of the Δflo11 and S288c strains. L-histidine dramatically decreases air-liquid biofilm formation and adhesion to polystyrene of the flor yeasts with no effect on the transcription level of the FLO11 gene. Moreover, L-histidine modifies the chitin and glycans content on the cell-wall of flor yeasts[1].

DMSO : < 1 mg/mL (insoluble or slightly soluble)
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, 1 year; -20°C, 6 months. When stored at -80°C, please use it within 1 year. When stored at -20°C, please use it within 6 months.
* 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.

プロトコル
Rats: TAA (300 mg/kg i.p) is given to animals daily for 3 days. L-histidine (100 mg/kg) is dissolved in saline and injected (i.p.) daily 2 hours before each TAA injection. To prevent hypoglycemia and dehydration, rats are given 12.5 ml/kg of fluid therapy (5% dextrose and 0.45% saline with 20 mEq/L of potassium chloride) every 12 hours, s.c. Normal controls receive saline (vehicle used for TAA), whereas another group of rats are given L-histidine alone (100 mg/kg) daily for 3 days. TAA-treated rats are clinically monitored, and stages of encephalopathy are graded[2].
Mice: The control group is fed with the AIN-93G purified diet that contains 5.08 g L-histidine/kg, whereas the L-histidine diet group is fed with AIN-93G that contains 1.28 g L-histidine/kg (25% of the histidine content in AIN-93G). To equalize the total amount of amino acids, glutamine is added to the L-histidine diet to counterbalance the changes in the histidine content (18.32 g L-glutamine/kg AIN-93G vs. 23.72 g L-glutamine/kg L-histidine diet). Both diets are isonitrogenous. At 8 wk of age, the mice are weighed and assigned to 2 different diets. The mice are allowed ad libitum access to water and their respective diets, and they are housed for at least 2 wk in the laboratory before starting the experiments[3].
