DESCRIPTION
Application
Trichloroacetic acid has been used for the precipitation of sLRP (soluble circulating low density lipoprotein receptor-related protein-1) isolated from plasma.
It has been used for the extraction of ascorbic acid from plant samples.It has also been used for the preparation of ascorbate standards for ascorbate assay.
It has been used for the precipitation of IMAC (immobilized metal ion affinity chromatography)-isolated phosphoproteins.
Traditionally used to precipitate protein. Has been used to determine protein concentration by quantitative precipitation. Used as decalcifier and fixative in microscopy.
