?產(chǎn)品信息：
經(jīng)Nuclear Fast Red (cat#H-3403)復(fù)染的細(xì)胞核呈粉紅色。其尤其適用于多抗原標(biāo)記的多重染色，可與其他靶標(biāo)蛋白形成鮮明的顏色對比。此外，該產(chǎn)品為即用型試劑，使用方法簡單，操作快速。
?產(chǎn)品特點(diǎn)：
??1. 簡單、快速，一步即可完成染色；
??2. 多抗原標(biāo)記的最佳選擇，可避免蘇木精導(dǎo)致的模糊染色；
??3. 與多種底物相兼容，并形成良好的顏色對比；
??4. 適用于非水溶性封片劑

復(fù)染——作為免疫組化實(shí)驗(yàn)的最后一個步驟，其重要性不言而喻。
通過復(fù)染，可對特定的細(xì)胞結(jié)構(gòu)進(jìn)行染色，有助于實(shí)現(xiàn)對靶標(biāo)蛋白的定位以及可視化觀察，更有利于闡述組織切片形態(tài)學(xué)特征和細(xì)胞內(nèi)部結(jié)構(gòu)。Vectorlabs公司可提供多種核復(fù)染試劑：Hematoxylin、Hematoxylin QS、Methyl Green、Nuclear Fast Red等。產(chǎn)品包裝方便、均為即用型試劑，可用于單個載玻片或整個染色皿的染色。
