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.

Enzymatic Assay of Proteinase K with Hemoglobin Substrate

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).

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.

Universal Protease Activity Assay: Casein as a Substrate

Proteases break peptide bonds. In the lab, it is often necessary to measure and/or compare the activity of proteases. Sigma's non-specific protease activity assay may be used as a standardized procedure to determine the activity of proteases, which is what we do during our quality control procedures.

Universal Protease Activity Assay using Casein as a Substrate

Measure and compare the activity of proteases with this non-specific protease activity assay using casein. Use this assay as a standardized procedure to determine the activity of proteases for quality control.
