| Application: | Trichloroacetic acid solution has been used: • in indoleamine 2,3-dioxygenase (IDO) enzyme assay to hydrolyze N-formylkynurenine and produce kynurenine • in the proliferation of human pulmonary artery smooth muscle cells (HPASMCs) • to treat ground tissue and precipitate proteins during protein extraction and quantification |
| Biochem/physiol Actions: | Trichloroacetic acid solution is traditionally used to precipitate protein. It can be used to determine protein concentration by quantitative precipitation. Trichloroacetic acid can also be used as a decalcifier and fixative in microscopy. |
| Biochem/physiol Actions: | Trichloroacetic acid (TCA) with no known systemic toxicity, is used as a time-honored agent for superficial peeling. It is a peroxisome proliferator. |
| General description: | Trichloroacetic acid (TCA) is a strong acid. At the pH of drinking water, TCA exists almost in salt form. |
