生物活性
方法:6 种儿童白血病和淋巴瘤细胞系 NALM-6、 NALM-16、JURKAT、CEM、RAMOS 和 NAMALWA 用 Methotrexate (0.002-5 μM) 处理 120 h,使用 SRB 方法检测细胞增殖抑制活性。
结果:Methotrexate 对肿瘤细胞的 IC 50 中位数为 78 nM,对六种肿瘤细胞的 IC50 在 33-133 nM 之间。[1]
方法:人卵巢癌细胞 SKOV-3 用 Methotrexate (15-50 μM) 处理 24 h,使用 AO/EtBr probe 检测细胞凋亡情况。
结果:Methotrexate 诱导 SKOV-3 细胞凋亡。[2]
方法:为检测慢性毒性,将 Methotrexate (0.25-6 mg/kg) 腹腔注射给 C57BL/6、DBA/2 和 C3H小鼠,每周五次,持续 12-18 个月。
结果:0.25-2 mg/kg 剂量下的耐受性良好,淋巴组织、睾丸和皮肤中的细胞抑制最小。3-6 mg/kg 剂量下会产生众所周知的急性至亚急性造血和胃肠道损伤,导致早期死亡。[3]
方法:为检测在不同类型风湿性关节炎 (RA) 和多发性硬化症 (MS) 模型中的作用模式,将 Methotrexate (0.1-5 mg/kg) 腹腔注射给不同发病机制的 RA 和 MS 模型,每天一次,持续十四天。
结果:Methotrexate 对 CIA、PIA 等经典 RA 模型及 MS、EAE 模型均有较强的改善作用。Methotrexate 仅在 T 细胞活化之前和依赖于 T 细胞活化的疾病中起作用。[4]

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
