中文名称:总谷胱甘肽/氧化型谷胱甘肽测定试剂盒(分光光度法)
英文名称:Toal glutathione / Oxidized glutathione assay kit
产品规格:50管
发货周期:1~3天
检测指标:总谷胱甘肽;T-GSH;氧化型谷胱甘肽;GSSG
本试剂盒可测各种动物血清(浆)、组织、全血、红细胞等样本。谷胱甘肽在机体内的广泛分布和多功能性愈来愈引起科研工作者的注意。它在许多重要的生物体现象中起着直接或间接的作用,因而涉及到许多不同的研究课 题,如酶反应机理,蛋白质和DNA等大分子的生物合成、中间代谢、辐射、肿瘤、免疫、环境毒素和老化等。特别是近年来许多研究课题都涉及到细胞对活性氧和 自由基的防御作用。其中测定生物样品中,特别是血清(浆)中还原型和氧化型谷胱甘肽(GSH和GSSG)含量变化,是机体氧化物牵累的重要指标。
优点如下:
1、快速简便:全程约40分钟,可测80例左右样本;
2、取样量微:常规操作取样量50l, 酶标仪操作仅需5l即可测样本中的ACP活力;
3、稳定性好:试剂盒2~8℃存放3个月有效;
4、再现性好:变异系数CV=1.2%,20倍稀释线性仍然良好;
5、回收试验: X =96%;
6、受外界影响因素小:干扰因素少,重复性强;
7、测试面广:可测动物血清(浆)、组织、各种体液、灌流液、各种培养细胞以及细胞培养上清液等。
总谷胱甘肽/氧化型谷胱甘肽测定试剂盒(分光光度法) 细胞生物学研究有以下几个方面:
细胞生物学的研究内容十分广泛,主要包括:
①细胞核、染色体以及基因表达的研究;
②生物膜与细胞器的研究;
③细胞骨架体系的研究;
④细胞增殖及其调控;
⑤细胞分化及其调控;
⑥细胞的衰老与编程性死亡(凋亡);
⑦细胞的起源与进化;
⑧细胞工程.
细胞生物学研究的常用技术有哪些:
1.显微技术:包括显微观察,显微操作.
2细胞组分分析技术:离心分离技术,生物大分子定位技术,定量细胞化学分析技术.
3.细胞工程:细胞培养。
注意事项:
1. 本试剂盒的检测试剂中含有萤光素酶,反复冻融会导致其逐渐失活。尽管经测试本试剂反复冻融5次对于其检测效果无显著影响,为取得良好的使用效果,*次解冻后可适当分装保存。反复冻融过程中,可能会导致检测试剂中出现少量沉淀,此时宜平衡至室温,并尽量溶解。如仍有残留的不溶物,可以离心去除后使用,经测试不会影响后续的检测效果。
2. 检测时需使用白色或黑色的96孔板或384孔板。如果使用普通透明的96孔板或384孔板,相邻孔之间会产生相互干扰。
3. 使用说明中提供了检测ATP标准品的方法,实际检测细胞活力时通常并不需要检测ATP标准品。

文献和实验发光基团pNA游离出来,可通过酶标仪或分光光度计(λ=405nm 或400nm)测定其吸光值,通过测定吸光度来检测Caspase的活性。 二、自备试剂 PBS、蛋白定量试剂盒(Bradford法,选用) 三、实验操作指南 1.准备工作: A、 裂解液溶解后混匀,冰浴备用。 B、 裂解液工作液制备:每50 μL裂解液中加入0.5 μL DTT,冰浴备用。 2.样本处理: A、悬浮细胞 1) 诱导完成后的细胞,2000 rpm离心5 min,弃上清,收集细胞,PBS轻轻重悬细胞并计数
度。 (2) 吸收系数法 按各品种项下的方法配制供试品溶液,在规定的波长处测定其吸收度,再以该品种在规定条件下的吸收系数计算含量。用本法测定时,应注意仪器的校正和检定。 (3) 计算分光光度法 采用计算分光光度法应慎重。本法有多种,使用时均应按各品种项下规定的方法进行。当吸收度处在吸收曲线的陡然上升或下降的部位测定时,影响精度的因素较多,故对照品和供试品测试条件应尽可能一致。若测定时不用对照品,如维生素A测定法,则应在测定时对仪器作仔细的校正和检定。
一、测定溶液中物质的含量 可见或紫外分光光度法都可用于测定溶液中物质的含量。测定标准溶液(浓度已知的溶液)和未知液(浓度待测定的溶液)的吸光度,进行比较,由于所用吸收池的厚度是一样的。也可以先测出不同浓度的标准液的吸光度,绘制标准曲线,在选定的浓度范围内标准曲线应该是一条直线,然后测定出未知液的吸光度,即可从标准曲线上查到其相对应的浓度。 含量测定时所用波长通常要选择被测物质的最大吸收波长,这样做有两个好处: ⑴灵敏度大,物质在含量上的稍许变化将引起较大的吸光度差异; ⑵可以避免
