体外研究
(In Vitro)

Isoniazid (INH) 是一种前体药物，必须被结核分枝杆菌中称为 KatG的细菌过氧化氢酶-过氧化物酶激活^[1]。
KatG 将等烟酰基与NADH偶联形成等烟酰基-NADH 复合物。该复合物与称为 InhA 的烯酰-酰基载体蛋白还原酶紧密结合，从而阻断天然烯酰-AcpM 底物和脂肪酸合成酶的作用。该过程抑制分枝杆菌细胞壁所需的分枝菌酸的合成。KatG 激活 Isoniazid 会产生一系列自由基，包括一氧化氮，这也被证明对另一种抗分枝杆菌前药 PA-824 的作用很重要^[2]^[3]。
Isoniazid 对快速分裂的分枝杆菌有杀菌作用，对生长缓慢的分枝杆菌有抑菌作用^[4]。

* 请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液；一旦配成溶液，请分装保存，避免反复冻融造成的产品失效。
储备液的保存方式和期限：-80°C, 6 months; -20°C, 1 month (protect from light)。-80°C储存时，请在6个月内使用，-20°C储存时，请在1个月内使用。

* 备注：如您选择水作为储备液，请稀释至工作液后，再用 0.22 μm 的滤膜过滤除菌后使用。

摩尔计算器
稀释计算器

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

Concentration _(start) × Volume _(start) = Concentration _(final) × Volume _(final)

This equation is commonly abbreviated as: C₁V₁ = C₂V₂

动物实验：

以下溶解方案，请直接配制工作液。建议现用现配，在短期内尽快用完。以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比；如在配制过程中出现沉淀、析出现象，可以通过加热和/或超声的方式助溶。

方案一

请依序添加每种溶剂： PBS
Solubility: 150 mg/mL (1093.77 mM); 澄清溶液; 超声助溶

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
