文献和实验Cesium Chloride Purification of T7
, and very gently resuspend the pellet in 3.5 mL of T7 Buffer. Centrifuge the lysate at 5,000 rpm for 10 min, and keep the supernatant. Pour a cesium chloride step gradient: add 0.5 mL of cesium chloride with a density of 1.6 to the bottom of a centrifuge tube
Measurement of Chloride Movement in Neuronal Preparations
, protocols are described for biochemical and optical techniques that have been used by investigators to measure ligand?gated chloride movement in vesicular structures called synaptoneurosomes (also referred to as microsacs), in cultured neurons
尿素酶试验检测Hp 试剂 中通常加有一定量的缓冲成分,可以避免返流的胆汁及十二指肠液的影响[Am J Gastroenterol 1987;82:200],但会延长观察结果的时间,观察时间太短易出现假阳性[Lancet 1985;1:1443;1986;1:149]。我们研制的1min检测液中,不含有缓冲成份,从而使Hp尿素酶分解尿素导致的Hp变化能迅速被探知。本组1min法检测Hp的阳性率和特异性分别为97.8%和100%(以涂片法检查为标准),且符合简便、快速
