Solvent & Solubility
1 M HCl : 25 mg/mL (93.16 mM; ultrasonic and warming and heat to 60°C)
H2O : 8.7 mg/mL (32.42 mM; ultrasonic and adjust pH to 2 with 1 M HCL)
H2O : 1.67 mg/mL (6.22 mM; ultrasonic and warming and adjust pH to 2 with HCl and heat to 60°C)
DMSO : 1 mg/mL (3.73 mM; ultrasonic and adjust pH to 5 with HCl; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
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, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.
* 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.

Protocol
Mice[1]
Groups of mice are first injected on GD 8 with a single dose of 75 mg/kg of L-Homocystine or an equal volume of saline. One half of the L-Homocystine-treated animals then receive a single dose of 600 mg/kg of VPA ((H-HoCys-OH)2+VPA group), while the other half are injected with a proportionate volume of saline (L-Homocystine+saline group). In the other experiment, mice are treated with a daily dose of 75 mg/kg of L-Homocystine or a proportionate volume of saline starting from GD 5 and continue through GD 10. One half of the L-Homocystine-treated animals also have a single exposure to 600 mg/kg of VPA (L-Homocystine+VPA group) or a proportionate volume of saline (L-Homocystine+saline group) on GD 8. The total volume of fluid injected corresponded to the body weight and does not exceed 0.45 mL[1].
