Effects of some enzymes on the turbidity of a TSL suspension. In experiment A, TSL was sus- pended in 0-iM-tris-maleate buffer pH 7-3. In experiment B, the buffer was o-iM-tris, pH 7-9, except that o-iM-phosphate, pH 6-6, was used when digestion was with pepsin. The concen- tration of TSL was approximately 0-25 Concentrations of enzymes were: trypsin (crystal- hzed), o-i ; a-chymotrypsin (from ethanol), o-i ; pepsin (crystallized), 0-

In phosphate buffer pH 6*3, only one component (mobility 4-06 x io~^ cm.^ ;^ volt~^) was evident. The mobilities of both components at pH 8 • 6 were considerably.
