We developed a rapid step-gradient HPLC method for determination of glutamate, glycine and taurine, and a separate
我们开发了一个快速step-gradient反相高效液相色谱法测定麸胺酸、甘氨酸、牛磺酸、和一个单独的
method for determination of g-aminobutyric acid (GABA) in striatal microdialysates. The amino acids were pre-column
方法测定g-aminobutyric酸(GABA)microdialysates纹状体。pre-column的氨基酸
