Description

Application

Traditionally used to precipitate protein. Has been used to determine protein concentration by quantitative precipitation. Used as decalcifier and fixative in microscopy.

Trichloroacetic acid has been used:

• for hydrolysis of DNA isolated from the cell
• for precipitation of glutathione isolated from seminal plasma
• as a fixative in microscopy

General description

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