一般說明

氯化钠是一种重要的营养素,有助于维持人类和动物的正常身体机能。这种化学物质在自然界中普遍存在,具有广泛的生物化学应用,如静脉输液和密度梯度。它也被用作稀释剂,以增加缓冲液或培养基中的离子强度。氯化钠是维持血浆渗透压和身体的细胞外液体积所必需的。过量NaCl会导致血压升高,这会导致心血管和肾脏疾病。无菌 NaCl是滴眼液的一种成分。传统上,使用高浓度盐可保存食物,因为大多数细菌不能在高盐条件下生长。

應用

氯化钠溶液可用作以下溶液的组分:
  • 聚乙二醇(PEG)缓冲液,用于纯化双标记的产物
  • NT2 缓冲液,用于制备抗体包被的蛋白A琼脂糖(PAS)凝珠和免疫沉淀的核糖核蛋白(RNP)
  • 冷冻用于从小鼠肾脏中分离单核的裂解缓冲液

特點和優勢

  • 地质上稳定
  • 适合提纯、沉淀、结晶
