應用

琼脂糖用于核酸的制备和分析分离。它可用于单细胞凝胶电泳测定。它还可用于southern印迹杂交。它也可用于评估来自培养的新生大鼠半圆形管上皮的跨上皮离子通量。

生化/生理作用

琼脂糖是一种多糖,用于500-20,000 bp的消退DNA和RNA片段。它提供了强大的凝胶结构,有助于更好的处理和更少的破裂。它还可以在琼脂糖凝胶培养过程中从去分化的软骨细胞重新表达分化的胶原表型。

分析報告

以下是与我们的琼脂糖相关的性质列表:
硫酸盐含量 - 用作纯度指标,因为硫酸盐是其中存在的主要离子基团。
凝胶强度 - 破裂凝胶所需施加的力。
胶凝点 - 琼脂糖水溶液在冷却时的胶凝温度。 琼脂糖溶液在液体-凝胶转变的过程中会表现出滞后现象 - 也就是说,它们的凝胶点与它们的熔点温度不同。
电内渗(EEO)- 液体通过凝胶的一种运动。琼脂糖凝胶中的阴离子基团被固定在基质上不能移动,但可解离的抗衡阳离子可以向基质中的阴极迁移,从而产生EEO。 由于生物聚合物的电泳运动通常是朝向阳极的,因此EEO会因为内部的对流而破坏分离。
