一般說明

硫氧还蛋白还原酶检测试剂盒采用比色法对哺乳动物细胞核组织中的硫氧还蛋白还原酶进行检测。该试剂盒原理是硫氧还蛋白还原酶可催化NADPH使5,5′-二硫双(2-硝基苯甲酸) (DTNB)还原成5-硫代-2-硝基苯甲酸(TNB)，后者在412nm处呈现强黄色。

DTNB + NADPH + H+ ↔ 2 TNB + NADP+

應用

使用大鼠肝去除细胞核后的提取物，本试剂盒的线性度可达0.25单位/ml。在该试剂盒反应中，约20%的活性是非特异性还原酶的活性。(TrxR抑制剂对其无效).

特點和優勢

  • 检测方法简单易行。
  • 试剂盒中包含了比色法检测哺乳动物硫氧还蛋白还原酶所需的所有试剂。
  • 试剂盒中提供了特异性抑制哺乳动物硫氧还蛋白还原酶的溶液。
  • 该试剂盒已通过心肌和HeLa, A549, Jurkat, U937, A431, COS, CHO 和 NIH 3T3 等细胞系裂解物的测试。

Helicobacter pylori (H. pylori) infection poses a worldwide public health crisis, as chronic infection is rampant and can lead to gastric ulcers, gastritis, and gastric cancer. Unfortunately, frontline therapies cause harmful side effects and are often ineffective due to antibiotic resistance.

Platelets are central to normal hemostasis and must be tightly controlled to prevent thrombosis. However, drug treatments that also affect platelets could lead to unwanted side effects on hemostasis or thrombosis. In this study, the effect of auranofin on platelets

Cancer cells (relative to normal cells) show increased steady-state levels of hydroperoxides that are compensated by increased glucose and hydroperoxide metabolism. The current study determined whether inhibitors of glucose and hydroperoxide metabolism could induce chemoradiosensitization by enhancing oxidative stress in
