产品描述

General description

Trichloroacetic acid (TCA) is an important metabolic product of trichloroethylene (TCE) metabolism.

Application

Trichloroacetic acid has been used:
• for protein precipitation^[3]
• as a component in the extract solution used for the measurement of malondialdehyde and glutathione^[4]
• to precipitate the transfected and treated cells in [³H]-thymidine incorporation assay^[5]
已使用三氯乙酸：
•用于蛋白质沉淀
•作为萃取溶液中的成分，用于测量丙二醛和谷胱甘肽
•在[3H]-胸苷掺入法中沉淀转染和处理的细胞

传统上用于沉淀蛋白质。用于通过定量沉淀测定蛋白质浓度。用作脱钙剂和显微镜样品的固定剂。

包装

100, 250, 500 g in glass bottle
