General description

氯化钠又称石盐,是自然界最常见的矿物质之一。它是一种公认的电解质,可通过控制渗透压和水平衡,维持细胞完整性和体内平衡。由于具有抗菌特性,氯化钠在食品工业广泛用作食品添加剂和防腐剂。还可将其加入实验室缓冲液,增加离子强度。NaCl 也可用于 DNA 提取。钠和氯是生物机能中的主要电解质。

Application

氯化钠已用于:
  • 配制PBS(磷酸盐缓冲盐水)溶液。
  • 气管软骨组织样品脱细胞前的预处理。
  • 作为细菌培养用胰蛋白酶大豆琼脂培养基的成分。
  • 配制裂解缓冲液。
这种物质还可与碳酸氢钠配合使用,以调节体液酸碱平衡。

Features and Benefits

通过微量元素杂质测试,确保高纯度。
