Analysis Note
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。

Elevated triglycerides are associated with an increased risk of cardiovascular disease, and lipoprotein lipase (LPL) is the rate-limiting enzyme for the hydrolysis of triglycerides from circulating lipoproteins. The N-terminal domain of angiopoietin-like protein 4 (ANGPTL4) inhibits LPL activity. ANGPTL4 was

In most pluripotent stem cell differentiation protocols the formation of embryoid bodies (EBs) is an important step. Here we describe a rapid, straightforward soft lithography approach for the preparation of hydrophilic silicon masters from different templates and the subsequent production
