一般說明

甲基紫 2B 是聚甲基化(4、5 和 6)副品红的混合物

應用

甲基紫2B已被用于在体外抗病毒测定中对人肺成纤维细胞(A549)进行染色。

生化/生理作用

甲基紫2B是一种具有三苯甲烷结构的阳离子染料。 它作为一种选择性染料,有助于区分肺炎克雷伯菌(Klebsiella pneumoniae )与产气肠杆菌(Enterobacter aerogenes )和其他革兰氏阴性菌。 甲基紫2B的吸入、吞咽或皮肤吸收将产生有害作用,接触皮肤和眼睛可能会造成伤害。因此,染料清除工作非常重要。

適合性

经认证可用于染色体的弗来明氏碘三重染色、染色质和核仁的牛顿结晶紫-碘染色技术以及 Lieb淀粉样染色。
