一般說明
N-N-双(2-羟乙基)-2-氨基乙磺酸（BES）是一种两性离子缓冲液，常用于生物化学和分子生物学研究中。BES缓冲液可用作二级pH标准物质，能使溶液保持在稳定的pH范围内，特别是在6.2-7.6范围内。一项研究表明，在细菌内毒素检查中使用这种缓冲液可以最大限度地减少干扰因素的影响。BES还可用作磷酸钙介导质粒DNA转染真核细胞的缓冲溶液。
應用
BES缓冲液可用于：
- 作为体外分析胸腺细胞凋亡时培养胸腺细胞用的opti-minimal essential medium（MEM）培养基的补充剂
- 作为腺相关病毒（AAV）载体制备、提取和纯化用的硼酸盐缓冲液（BBS）的组分
- 作为精液采集和冷冻保存用的稀释剂之一的组分

Stent fracture is important because it may cause adverse events. The interventional cardiologist needs independent data to aid stent selection. Stent designers need data to improve stent design. We used a repetitive bend test to compare durability and fracture for

Coronary adventitia harbors a wide variety of components, such as inflammatory cells and vasa vasorum (VV). Adventitial VV initiates the development of coronary artery diseases as an outside-in supply route of inflammation. We have recently demonstrated that drug-eluting stent implantation

Colloidal CdSe quantum dot (QD) core ensembles were photodimmed and allowed to recover in the dark using ambient thermal energy at a range of temperatures. Nonlinear thermal recovery is well described by a stretched exponential function, and further analysis yields

Numerous studies have demonstrated an association between endothelial shear stress (ESS) and neointimal formation after stent implantation. However, the role of ESS on the composition of neointima and underlying plaque remains unclear. Patients recruited in the Comfortable AMI-IBIS 4 study
