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.

Protocols

Enzymatic Activity of Glucose-6-Phosphatase [EC 3.1.3.9]

To measure glucose-6-phosphatase activity, the Taussky-Shorr method is used. This method is a spectrophotometric stop-rate determination assay that is measured at 660 nm.

Enzymatic Assay of Pepsin (3.4.23.1)

This procedure may be used for determination of Pepsin activity using hemoglobin as the substrate. It is a spectrophotometric stop rate determination.

Enzymatic Assay of Amyloglucosidase (EC 3.2.1.3)

This procedure may be used for the determination of Amyloglucosidase activity using starch as the substrate.

Enzymatic Assay of Proteinase K (EC 3.4.21.64)

Proteinase K (EC 3.4.21.64) activity can be measured spectrophotometrically using hemoglobin as the substrate. Proteinase K hydrolyzes hemoglobin denatured with urea, and liberates Folin-postive amino acids and peptides. One unit will hydrolyze hemoglobin to produce color equivalent to 1.0 μmol of tyrosine per minute at pH 7.5 at 37 °C (color by Folin & Ciocalteu's Phenol Reagent).
