以下是细胞生物学试剂的详细介绍:
中文名称:氢-钾ATP酶(H+、K+-ATPase)试剂盒
英文名称:H+、K+-ATPase assay kit
产品规格:200管/96样|100管/48样
发货周期:1~3天
检测指标:氢-钾ATP酶;H+、K+-ATPase
本试剂盒可测各种动物组织、培养细胞等样本中的H+K+-ATP酶活力。H+K+-ATPase对胃酸的分泌及胃的消化功能具有重要的生理意义,70年代Forte等人首先在牛蛙的胃粘膜上分离出一类能被K+专一激活而不被乌本苷抑制的ATPase即H+K+-ATPase,随后Lee·j等人又证明了含有该酶的膜囊泡运动跨膜运输质子的作用,从而为胃酸分泌的机理奠定了分子学基础,H+K+-ATPase定位于胃粘膜壁细胞(Parietal lell)上,属于第二类质子泵,它通过自身的磷酸化(E1→E2)与去磷酸化(E2→E1)完成的H+/K+电中性(electroneutral)跨膜离子转运,不断将壁细胞内的质子运输到膜外行使泌酸的功能。
ATP酶可分解ATP生成ADP及无机磷,测定无机磷的量可判断ATP酶活力的高低。H+K+—ATP酶是一种能被钾专一激活而不被乌本苷抑制的ATP酶。
优点如下:
1、快速简便:全程约50分钟,可测100例左右样本。
2、取样量微:本法取样本量100ul。
3、稳定性好:试剂盒2~8℃存放6个月有效。
4、再现性好:变异系数CV=1.7%。
5、回收试验: X =103.3%。
6、受外界影响因素小:干扰因素少,重复性强。
7、测试面广:可测动物组织、红细胞以及各种培养细胞、各种水产等,效果均佳。
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。

文献和实验血症,又可导致低氯血症。已经证明,任何原因引起的低氯血症均可使肾排钾增多。其可能机制之一是低氯血症似能直接剌激远侧肾小管的泌钾功能。 ②某些肾脏疾病:如远侧肾小管性酸中毒时,由于远曲小管泌氢功能障碍,因而H+-Na+交换减少而K+-Na+交换增多而导致失钾。近侧肾小管性酸中毒时,近曲小管HCO3-的重吸收减少,到达远曲小管的HCO3-增多是促进远曲小管排钾增多的重要原因(详后文)。急性肾小管坏死的多尿期,由于肾小管液中尿素增多所致的渗透性利尿,以及新生肾小管上皮对水、电解质重吸收的功能不足
,DCC)可与F0的DCC结合蛋白结合,阻断H+通道,抑制ATP合成。栎皮酮(quercetin)直接抑制参与ATP合成的ATP酶。 (三)解偶联剂(uncoupler) 解偶联剂使氧化和磷酸化脱偶联,氧化仍可以进行,而磷酸化不能进行,解偶联剂作用的本质是增大线粒体内膜对H+的通透性,消除H+的跨膜梯度,因而无ATP生成,解偶联剂只影响氧化磷酸化而不干扰底物水平磷酸化,解偶联剂的作用使氧化释放出来的能量全部以热的形式散发。动物棕色脂肪组织线粒体中有独特的解偶联蛋白,使氧化磷酸化处于解偶联状态
。许多利尿药还有一个引起肾排钾增多的共同机制:通过血容量的减少而导致醛固酮分泌增多。速尿、利尿酸、噻嗪类的作用在于抑制髓袢升支粗段对Cl-的重吸收从而也抑制了Na+的重吸收。所以,这些药物的长期使用既可导致低钠血症,又可导致低氯血症。已经证明,任何原因引起的低氯血症均可使肾排钾增多。其可能机制之一是低氯血症似能直接剌激远侧肾小管的泌钾功能。 ②某些肾脏疾病:如远侧肾小管性酸中毒时,由于远曲小管泌氢功能障碍,因而H+-Na+交换减少而K+-Na+交换增多而导致失钾。近侧肾小管性酸中毒时
