solubility
soluble (Preparing a Nitrocefin (500 µg/ml) Solution
• Dissolve 1 mg Nitrocefin in 100 µl dimethylsulfoxide (DMSO) and vortex.
• Add 1.9 ml phosphate buffer (100 mM, pH 7) to produce 2 ml total volume.
• This yields a working Nitrocefin solution of 500 µg/ml (~1 mM), which is suitable for most applications.
• Nitrocefin, particularly in solution, is very sensitive to light.)

Preparation Note
•将1 mg头孢硝噻吩溶于100 µl二甲亚砜（DMSO）中并涡旋。
• 加入1.9 ml磷酸盐缓冲液（100 mM，pH值7），以产生2 ml总体积。
•这样就产生了500 µg/ml（〜1 mM）的头孢硝噻吩工作溶液，适用于大多数应用。
•头孢硝噻吩对光非常敏感， 特别是在溶液中时。
