低凝胶温度的琼脂糖

Agarose is a component of agar that is naturally found in the cell wall of red algae. It is hydrophilic and has a high gelling property. It is most commonly employed for gel electrophoresis, to form porous gels to analyze DNA, RNA, or proteins by size. When a voltage is applied to the system the charged nucleic acids migrate through the agarose gel and are separated by size. The stability and gelling properties of agarose make it versitile and it can be used for many other applications in research such as, plaque and comet assays, and even as a scaffolding agent to name a few.

Low-gelling agarose has been used in research:

• for gel electrophoresis, low melting temperature is ideal for DNA extraction from gel -gel scaffold material for tissue engineering using BMSCs
• to embed tissues in 5% agarose for immunohistology
• for preparation of collagen-agarose co-gels to study collagen-matrix interactions in soft tissues
• single-celled gel electrophoresis (comet assay)
• for in-vivo 3-D imaging of zebrafish larvae immobilized on agarose strips

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。
