General description

Trichloroacetic acid (TCA) is a strong acid. At the pH of drinking water, TCA exists almost in salt form.

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.
Trichloroacetic acid (TCA) with no known systemic toxicity, is used as a time-honored agent for superficial peeling. It is a peroxisome proliferator.

Microenvironmental factors contribute to the immune dysfunction characterizing acute myeloid leukemia (AML). Indoleamine 2,3-dioxygenase 1 (IDO1) is an interferon (IFN)-γ-inducible enzyme that degrades tryptophan into kynurenine, which, in turn, inhibits effector T cells and promotes regulatory T-cell (Treg) differentiation. It
