應用

EDTA 为金属蛋白酶抑制剂,有效浓度为 1-10 mM。EDTA 可用作金属蛋白酶活性中心锌离子的螯合剂,并且还可抑制其他依赖金属离子的蛋白酶,例如依赖钙的半胱氨酸蛋白酶。作为抗凝血剂时,通常使用 EDTA 的二钠或三钾盐。最佳浓度为每 mL 血液 1.5mg。

準備報告

室温下溶于水的最大浓度可达 1.45M。该溶液的 pH 值约为 10 至 11,而且粘度较大。

Micronuclei (MNs) are extranuclear DNA-containing bodies and determining MN frequencies is a measure of genomic instability. An age-related increase in MN frequencies in lymphocytes has been quantified, but this effect has not yet been measured in nasal and buccal cells.

Here, we provide a protocol using chemical pulldown combined with mass spectrometry (LC-MS/MS) to identify drug targets in Plasmodium falciparum. This approach works upon the principle that a resin-bound inhibitor selectively binds its molecular target(s) in cell-free lysates. We describe
