Dear Customer:

The current international situation is complex and volatile, and uncertain tariff policies may potentially impact our product prices. Given these uncertainties, we value your understanding regarding order-related matters.

If you decide to place an order during this period, we reserve the right to adjust the price based on the evolving situation. We understand that market changes may cause inconvenience. We will negotiate with you if there’s a significant price fluctuation due to tariff policy changes before the order’s actual delivery, and in such cases we may adjust or cancel the order as necessary.

一般描述

碳酸钠通常被称为苏打粉。索尔末法用氯化钠和石灰石生产碳酸钠。[1]碳酸钠提高了稻草的预处理并提高了脱木素工艺。[2]碳酸钠在提取生物活性代谢物中得到应用,如环氧二萜和生物碱,并从萃取物中去除酸性化合物。[3]在盐诱导相分离萃取法(SIPSE)中,碳酸钠诱导相分离,提高了乙腈对等离子体的分配。[4]

应用

碳酸钠已可用于:
  • 利用 榄仁树 提取物抑制α-葡萄糖苷酶活性[5]
  • 作为酶联免疫吸附试验(ELISA)的碳酸氢盐/碳酸氢盐缓冲液的成分[6]
  • 作为 共生孢子 生长培养基中的一种成分[7]

生化/生理作用

缓冲液成分,可用于去除外周膜蛋白。
