SDSE所有详细试剂配方

SDSE所有详细试剂配方

SDSE所有详细试剂配方SDSE(Sodium dodecyl sulfate-electrolyte system)是一种常用的聚丙烯酰胺凝胶电泳缓冲液,主要用于蛋白质电泳分离。

SDSE的制备是根据一定的配方进行的,下面是SDSE的详细试剂配方:1.氯化钠(NaCl):18.3g溶解在1L去离子水中2.磷酸二氢钠(NaH2PO4):3.5g溶解在1L去离子水中3. 溴酚蓝(Bromophenol Blue):0.25g溶解在10mL水中4. SDS(Sodium Dodecyl Sulfate):10g溶解在1L去离子水中5. 甘油(Glycerol):10mL溶解在100mL去离子水中以上是SDSE的基础配方,下面是其制备步骤:1.将NaCl和NaH2PO4溶解在分别容量为1L的去离子水中,用磁力搅拌器搅拌均匀。

2.分别将溶解好的NaCl和NaH2PO4溶液倒入大容量烧杯中,混合均匀。

3.在pH计的帮助下调节缓冲液的pH值,使其在6.8-7.0之间。

4.加入溴酚蓝溶液,此时溴酚蓝的浓度为0.0025%,用磁力搅拌器搅拌均匀。

5.加入SDS溶液,用磁力搅拌器搅拌均匀。

注意,加入SDS时要小心,避免溅出。

6.最后加入甘油溶液,搅拌均匀。

甘油的添加主要是为了增加样品的密度,使其在凝胶中下沉更快。

SDSE的配方比较简单,主要成分包括NaCl、NaH2PO4、溴酚蓝、SDS和甘油。

其中,NaCl和NaH2PO4是缓冲液的主要组成部分,用于维持适当的离子强度和pH值;溴酚蓝用于着色样品,方便观察电泳结果;SDS主要起到断开蛋白质的二级结构和线性化作用;甘油则用于增加样品密度,使其在凝胶中下沉更快。

通过恰当的配方和制备步骤,可以获得高质量的SDSE缓冲液,用于蛋白质电泳分离和分析。

但需要注意的是,不同实验目的和要求可能需要微调配方中一些成分的浓度,因此在具体实验过程中,可以根据需要进行相应的调整。

萃取荧光法测定药物及体液中硫酸氢氯吡格雷含量练伟芹;龚爱琴;王露;朱霞石【期刊名称】《光谱学与光谱分析》【年(卷),期】2014(000)011【摘要】提出了简单、灵敏的测定药物及体液中硫酸氢氯吡格雷含量的荧光新方法。

利用荧光法研究了硫酸氢氯吡格雷与茜素红的作用,基于在盐酸介质中硫酸氢氯吡格雷能与茜素红形成离子对化合物,该化合物能被二氯甲烷萃取,当用428nm波长激发时在550nm左右能发射较强的荧光。

因荧光强度与硫酸氢氯吡格雷浓度在一定范围内存在定量关系,从而建立了测定硫酸氢氯吡格雷含量的新方法。

当盐酸溶液的浓度为0.3mol·L-1时,形成的离子对比较稳定,硫酸氢氯吡格雷浓度在1.0~11.0μg·mL-1范围内时离子对荧光强度与硫酸氢氯吡格雷浓度呈良好的线性关系,线性方程为F=53.32+35.01c(μg·mL-1),r=0.994,检出限为0.11μg·mL-1。

硫酸氢氯吡格雷在药物和人血清、尿液中的回收率分别为90.6%~99.3%,104.6%~109.3%,96.3%~105.0%,干扰实验表明常用药物辅料对它的测定没有干扰。

用本法测定了硫酸氢氯吡格雷片、人血清及尿样中硫酸氢氯吡格雷含量,结果令人满意。

实验结果表明本法快速,灵敏度高,准确度好,可用于实际样品中硫酸氢氯吡格雷含量的测定。

双环戊二烯解聚制备环戊二烯

双环戊二烯解聚制备环戊二烯工013(000087)吴美忠摘要本文进行了双环戊二烯气相解聚制备环戊二烯的实验研究。

采用双戊二烯与水共沸法进行汽化,大大减少了汽化器与反应器的结焦的可能性。

在管式反应器中考察了解聚温度、停留时间、原料组成等因素对解聚过程的影响。

经过500小时的连续实验,反应器未出现堵塞现象。

采用80%的粗双环为原料,经解聚可以得到97%以上的环戊二烯,350℃时解聚率为95%以上,DCPD的收率可达90%。

如采用双环戊二烯含量为90%以上的双环为原料,解聚后可以得到99%以上的环戊二烯。

结果表明,在本实验的工艺条件下,环戊二烯产量较高,有很好的工业发展前景。
