Figure 1From: Comparison of activity indexes for recognizing enzyme mutants of higher activity with uricase as modelInterference from HIU with the assay of absorbance at 308 nm after the lag time of 10 s for 0.30 mM uric acid under uricase action at 25°C. a. Effects of activities on interference in 0.10 M Tris–HCl buffer at pH 7.4 b. Effects of activities on interference in 0.20 M borate buffer at pH 7.4 c. Effects of reaction pH on interference in 0.10 M Tris–HCl buffer with final uricase activity at 103 U/L d. Effects of reaction pH on interference in 0.20 M borate buffer with final uricase activity at 103 U/L.Back to article page
