From: Development and application of assay for determining β-glucosidase activity in human saliva
β-glucosidase activity in 20 human saliva samples. Two control assays were performed using 0.1 M phosphate buffer with and without 25 μL almond β-glucosidase. The rate of reaction displayed on the y-axis is in units of change in absorbance per change in time (minutes). The samples are labelled 1–20. Samples with different letters (A–E) have significantly different rates (Tukey HSD0.05)
