Protoplast swelling induced by D16 antibodies. A solution of D16 antibodies was applied to the protoplast suspension to the concentrations indicated. The control (A) was obtained by applying a solution containing 0.05-strength phosphate-buffered saline (PBS) and bathing medium components. This control investigated the possible effect of the highest concentrations of PBS components, derived from the antibody stock solution. The means from 38 to 47 protoplasts (two experiments) are shown. Other details were as described for Figure 1.
