Comments p.4221 right column 3rd paragraph: "On the basis of the suction required for initial aspiration of a flaccid vesicle and pipet diameter (~5×10^-4cm), the curvature elastic modulus, B, is estimated to be on the order of 10^-12 dyn cm (erg), consistent with values derived from analysis of thermal fluctuations of vesicle contours and theoretical predictions [primary sources]."
