설명

애플리케이션

• 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.
