설명

일반 설명

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

애플리케이션

Trichloroacetic acid has been used:

• for protein precipitation
• as a component in the extract solution used for the measurement of malondialdehyde and glutathione
• to precipitate the transfected and treated cells in [³H]-thymidine incorporation assay

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

생화학적/생리학적 작용

TCA might act as a carcinogen, targeting liver. It might be used as an acid decalcifying agent. TCA helps in nuclear staining.
