Protein separation of saliva samples from a healthy control depleted of amylase using potato starch with different saliva (μL of saliva) to starch (μg of starch) ratios from 0.5:1 to 4:1. The figure shows the flow through fractions and the eluted fractions using 2 × SDS loading buffer. Arrowhead denotes amylase band. Control denotes undepleted saliva sample from a healthy control. L = Ladder, E = Eluate, Ctrl = Control.
