一般描述

蔗糖是一种由葡萄糖和果糖组成的双糖，在各种生物过程中是能量来源。在细胞生物学中，蔗糖用作冷冻保护剂，在冷冻和解冻过程中保持细胞活力。 它也被添加在培养基中作为补充，帮助维持渗透平衡，提高细胞存活率。在分子生物学中，蔗糖在 DNA 和 RNA 纯化的梯度溶液和细胞器分离的密度离心中非常重要。

应用

蔗糖已用于：
  • 对肾组织进行冷冻保护
  • 用作固体萌发培养基成分，帮助花粉粒发芽
  • 三苯基四唑氯化物（TTC）试验，检查花粉粒活力
  • 固定脑组织冷冻保护，以用于免疫组织化学

生化/生理作用

由于蔗糖的化学反应性有限，在大多数植物中用作运输和储存分子。它可用于构建细胞/细胞器分离的密度梯度。蔗糖可用作植物、昆虫和细菌培养基补充剂。此外，蔗糖还可用于多种酶促测定。

特点和优势

  • 非常适合分子生物学、细胞生物学和生化研究
  • 经过测试，确认低水平的重金属污染，确保各种应用的适用性
  • 经过测试，检测 DNase、RNase 和蛋白酶
  • 分子生物学级蔗糖，来源于甘蔗
