||P.1112 right column 2nd paragraph: "The number of vesicles in each pool is as yet undetermined. Using flash Ca2+ pulses, Parsons et al. (primary source 306) estimated that the DVP contained 830 vesicles. Only 10% of these vesicles are released within 140 ms from the flash-thus the size of the RRP would be ∼100 vesicles. Vitale et al. (primary source 392) found that each bovine chromaffin cell contained 17,000 vesicles, but only 200 of these were located within 50 nm of the plasmalemma (DVP). Steyer et al. (ref 360) followed the movements of GFP-labeled vesicles using microscopic methods. They separated a small RRP within a much larger DVP that turns over through addition of vesicles actively moving to docking sites as well as through the release and reversal of docking."
