Descripción

General description

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

Application

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

Tradicionalmente usado para precipitar proteínas. Se ha utilizado para determinar la concentración de proteína por gravimetría. Usado como descalcificador y fijador en microscopía.

Biochem/physiol Actions

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