一般說明

X-GlcA 是 β-半乳糖苷酶的显色底物,用于确定琼脂平板上生长的细菌中是否存在克隆的 DNA 插入片段。 X-GlcA 设计用于具有 lac+ 表型的重组细菌菌落的蓝白色选择中替代 X-Gal。

應用

适用于选择具有 lac+ 表型的重组细菌菌落。
X-GlcA 已用于根切片的组化染色,用于光学显微镜观察。
β-葡萄糖醛酸酶 (GUS) 基因检测的显色底物。

原則

当 X-GlcA 被 β-半乳糖苷酶水解时,所得产物将形成蓝色沉淀。在 X-GlcA 存在下生长的 Lac+ 菌落会变成深蓝色,从而易于区分 lac+ 和 lac- 菌落。

Contamination of food with multiantibiotic-resistant bacteria, particularly extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae, is considered a potential source for the wide dissemination of ESBL-producing bacteria in communities. However, little is known about the extent of contamination of food with ESBL-producing bacteria in

Today, diverse studies report the benefits of probiotics, such as inhibitory effects on pathogens, aid in the management or prevention of chronic intestinal inflammatory diseases or atopic syndromes, and support to the immune system. Potential beneficial applications abound, researchers continue to evaluate the effictiveness and clarify the mechanisms of action of probiotics.
