在犬脊髓组织中以结构明确的方式测量亮氨酸脑啡肽。快速组织获取程序可最大限度地减少脑啡肽代谢。对脑神经肽进行高效液相色谱纯化,然后对脊髓组织提取物中的亮氨酸脑啡肽进行场解吸质谱测量。定量在组织湿重 70 ng (126 pmol) g−1 或十亿分之 70 的水平下进行。亮氨酸脑啡肽的高级同系物 2ala-亮氨酸脑啡肽被用作内标。添加了肽标准品的一系列样品获得了直线统计数据。
Leucine enkephalin is measured in canine spinal cord tissue in a structurally unambiguous manner. A rapid tissue procurement procedure minimizes enkephalin metabolism. High‐performance liquid chromatography purification of brain neuropeptides is followed by field desorption mass spectrometric measurement of leucine enkephalin in spinal cord tissue extracts. Quantification is performed at the 70 ng (126 pmol) g−1of wet weight tissue, or 70 parts per billion level. The higher homolog of leucine enkephalin,2ala‐leucine enkephalin, is utilized as internal standard. Straight‐line statistics are obtained for a series of samples to which a peptide standard is added.
