琼脂糖，Agarose；Low EEO

General description

Agarose, a natural polymer^[1] is obtained from sea algae.^[3] This neutral linear polysaccharide is made up of d-galactose and 3,6-anhydro-l-galactose. These are connected alternatively with the help of glycosidic bonds.^[3] Agarose has high significance in gel electrophoresis and gel chromatography.^[2]

Application

Agarose has been used:
• to form the photosynthetic slab^[4]
• in comparative study, to compare it with native agar, and agarose of Gracilaria dura^[5]
• to estimate the amino acid concentrations in agarose and agar samples^[6]
• as immobilisation substrates for enzyme immobilisation^[7]

包装

25, 100 g in poly bottle

Biochem/physiol Actions

Agarose is used as bioink due because of its characteristic properties such as, biocompatibility, mechanical strength and gelling ability at low temperature.^[1]

Analysis Note

以下是与我们的琼脂糖相关的属性列表：
硫酸盐含量 - 用作一种纯度的指标，因为硫酸盐是存在的主要离子基团。
凝胶强度 - 施加在凝胶上让其破裂所必需的力。
凝胶点 - 琼脂糖水溶液在冷却时形成凝胶的温度。 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。
