产品名称: 丙二醛(MDA)测定试剂盒(TBA法)
产品概述:
丙二醛(Malomdialdehvde,MDA)是机体内的氧自由基攻击生物膜中的多不饱和脂肪酸,形成的脂质过氧化物,测试MDA的量可反映机体内脂质过氧化的程度,间接地反映出细胞损伤的程度。丙二醛是常用的膜质过氧化指标,在酸性和高温度条件下,可以与TBA反应生成红棕色的三甲川(3,5,5—三甲基恶唑-2,4-二酮),其最大吸收波长在532nm。
本试剂盒可测血清、血浆、乳汁等细胞外液;肿瘤细胞、红细胞、白细胞、各种培养细胞以及各种动植物组织等样本中MDA的含量。

保存日期:
本试剂盒自订购之日起一年内有效。

注意事项:
1. 加入试剂一后必须摇匀后再加入试剂二。
2. 离心后若上清浑浊,需适当增加离心转数或时间,保证测定吸光度时溶液澄清。
试剂配制:1. 试剂一:液体10ml,室温保存。(天冷时会凝固,需要适当水浴加温溶解直至透明方可使用。)
2. 试剂二:液体3ml,用时加167ml双蒸水混匀,4℃冷藏。
3. 试剂三:用时向粉剂中加入90℃-100℃的热双蒸水,在溶解过程中可适当加热,充分溶解后用双蒸水定容 至30ml,冷却至室温再加冰醋suan30ml,混匀,配好的试剂避光冷藏(冰醋suan自备)。
操作流程:
1. 样本收集与前处理 :
a. 血清(浆)可直接测定。
b. 红细胞:需要用蒸馏水将红细胞制备成溶血液(100倍溶血液)后测定。
c. 动物组织样本:可用生理盐水按重量/体积比为1/10制备成组织匀浆液,离心取上清测定。
d. 培养细胞、细菌、植物组织:常用PBS作为匀浆介质破碎后离心取上清测定。 混匀摇晃试管的次数(单位:次)
注:a*表示所取的样品量、标准品量、无水乙醇的量、试剂一的量,四者均相等。例如样品取0.1ml则标准品、无水乙醇、试 剂一也取0.1ml,若样品取0.2ml则标准品、无水乙醇及试剂一也取0.2ml。因吸光度与加样量呈正比曲线,因而结果不受影 响。
**一般情况下 , 标准管、空白管及对照管每批只需做1-2只,若样本不存在溶血、脂血现象,则对照管可以不测,用空白管来 代替对照管。
2. 按上表加入样本和试剂。漩涡混匀 , 试管口用保鲜膜扎紧 , 用针头刺一小孔 , 95℃沸水浴40min。
3. 取出后流水冷却,然后12000rpm,离心5min。
4.取上清,再次12000rpm,离心2min。
5. 取上清,532nm处,1cm光径,蒸馏水调零,测各管吸光度值 , 并按照下列公式进行计算。
