生物活性

Pyrimethamine (Pirimecidan) is a potent, orally active dihydrofolate reductase (DHFR) inhibitor. Pyrimethamine is an antimalarial agent. Pyrimethamine affects the nucleoprotein metabolism of malarial parasites by interference in the folic–folinic acid systems and affects cell division by inhibiting the conversion of dihydrofolate to tetrahydrofolate^[1]^[2].

连续给药周期超过半月以上，请谨慎选择该方案。

请确保第一步储备液溶解至澄清状态，从左到右依次添加助溶剂。您可采用超声加热（超声清洗仪，建议频次 20-40 kHz），涡旋吹打等方式辅助溶解。

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.
