TABLE 2.

Tissue volume percentages from 184 human islet preparations broken into IEQ counting size bins.

Size bin	50–100	100–150	150–200	200–250	250–300	300–350	350–400	>400
Mean	7.34%	15.23%	21.1%	16.27%	14.47%	12.40%	9.1%	4.07%
SEM	0.50%	0.70%	0.70%	0.70%	0.90%	0.90%	0.90%	0.70%

The bins centered around 150 μm account for nearly 37% of the total preparation volume, the rationale behind the 150 μm IEQ size.
