低凝胶温度的琼脂糖_25g

General description

Agarose is a component of cell wall polysaccharides of marine red algae. It has high gelling property and is hydrophilic. It exists in random coil conformation.^[1]

Application

Agarose, low gelling temperature has been used:
• in the single cell gel electrophoresis of glioblastoma multiforme cells for genotoxicity studies^[3]
• in the preparation of collagen-agarose co-gels^[4]
• in the embedding of shrimp brain sections^[5]

包装

5, 10, 25, 50, 100, 250 g in poly bottle

Biochem/physiol Actions

Agarose is used in enzyme immobilization^[1] and electrophoresis. It is also used in food and cosmetic industry.^[2]

Analysis Note

以下是与我们的琼脂糖相关的属性列表:
含硫量 -用作纯度指标，因为硫酸盐是主要的离子基团。
凝胶强度 -必须施加于凝胶上使其断裂的力。
凝胶点 -液体琼脂糖溶液冷却时形成凝胶的温度。 琼脂糖溶液在液体至凝胶转变过程中表现出迟滞现象，即凝胶点与熔融温度不同。
电内渗(EEO) -液体通过凝胶的运动。琼脂糖凝胶中的阴离子基团附着在基体上不能移动，但游离的反阳离子可以向基体的阴极迁移，从而产生EEO。 由于生物聚合物的电泳运动通常是向阳极方向的，由于EEO的内部对流，EEO可以干扰这些分离。
