After 5-30 at 37C trichloroacetic is added to stop the reaction and the resulting soluble peptides are spectrophotometrically detected at 280 nm, comparing absorbance with a tyrosine standard curve (48, 63)
For example, other studies show similar effects on: plasma measurement of DNA [40, 41], thiols [42], and creatinine [43]
