Trichloroacetic acid (TCA) ≥99.0%, powder ACS
Trichloroacetic acid (TCA)

Trichloroacetic acid is used in protein precipitation; has been used to determine protein concentration by quantitative precipitation. Used as a decalcifier and fixative in microscopy. A protocol for the precipitation of nucleic acids can be found in Molecular Cloning.
Stability: Long term storage of aqueous solutions of less than 30% strength is not recommended. Decomposition products are chloroform, hydrochloric acid, carbon dioxide and carbon monoxide. Chloride ≤0.001% ; Nitrate ≤0.002%; Phosphate ≤5 ppm; Sulfate ≤0.02%
