Opis ogólny

Trichloroacetic acid (TCA) is derived from Trichloroethylene (TCE) metabolism. It is used as an acid decalcifying agent. TCA is used as a fixative for nuclear staining and protein precipitation.

Zastosowanie

Trichloroacetic acid (TCA) has been used:
  • to determine its effect on avian embryos during an exposure window encompassing cardiac specification
  • as a cell fixative
  • to terminate the O-acetylserine (thiol)lyase (OASTL) enzymatic assay
  • for the precipitation of acidic ribosomal proteins (RPs)

Traditionally used to precipitate protein. Has been used to determine protein concentration by quantitative precipitation. Used as decalcifier and fixative in microscopy.
