其他说明

便于将 Trizma HCl 产品规格与 Trizma HCl 规格表进行比较。
所有缓冲液的pH值都与温度和浓度有关。对于 Tris 缓冲液，温度每降低 1°C，pH 就会增加约 0.03 单位，每稀释 10 倍，pH 会降低 0.03-0.05 单位。对于一些精准的应用，请使用经过仔细校准的pH计和玻璃/甘汞组合电极。

Drechmeria coniospora is a nematophagous fungus and potential biocontrol agent. It belongs to the Ascomycota. It is related to Hirsutella minnesotensis, another nematophagous fungus but, phylogenetically, it is currently closest to the truffle parasite Tolypocladium ophioglossoides. Together with its natural
