结晶紫(Crystal Violet)是最初在革兰氏染色技术中用于区分革兰氏阴性和革兰氏阳性菌的染料之一,染色原理在于不同的细菌其细胞壁化学结构不同。革兰氏阳性菌,即染色呈阳性菌体内保留有结晶紫-碘复合物,在显微镜下呈紫褐色。在组织培养试验中结晶紫可用于对细菌污染情况的评估。另外,结晶紫还可用于区分不同古生菌以及用于肿瘤细胞系生长抑制或毒性分析。结晶紫还可用作非水溶液酸碱滴定指示剂。
本品为结晶紫粉末,可根据具体的实验要求配制不同浓度的结晶紫染色液。也可直接购买0.5%结晶紫染色液(货号:60506ES60),用作细胞染色用途。或者2%结晶紫染色液,与番红染液结合使用,以区分革兰氏阳性和阴性菌。
本产品是一种三苯甲烷类碱性染料,化学性质稳定,在常温下不易分解。
