Effect of medium components on the cytidine assay.

Note: Values reported in the table were the average of three parallel determinations. The absorbance was reported as a percentage of that obtained with cytidine, (2 mM) dissolved in water, i.e., ((absorbance with cytidine + test compound)/absorbance with cytidine alone) × 100%. A value of 100 means no interference; a value of 0 means total interference, i.e., no color formation at all, and values greater than 100 mean the test compound enhances the absorbance of the solution.Effect of medium components on the cytidine assay.
