产品描述

General description

Trichloroacetic acid (TCA) is produced during the chlorination of water comprising natural organic material.[1] It is a novel reagent used in clinical laboratories for deproteinization of body fluids.[4] In addition, TCA is also used in the treatment of genital warts[2] and acne scars.[3]

Application

Trichloroacetic acid has been used:
• for hydrolysis of DNA isolated from the cell[5]
• for precipitation of glutathione isolated from seminal plasma[6]
• as a fixative in microscopy[7]

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。
