Capsule size and strength tests

So other QC tests that we do are really focused on the capsules themselves rather than the islets, and these are tests where we’re looking at the uniformity of the capsules, the size of the capsules, the quality of the coating. And the capsule obviously is key to our process because it protects the islet from the immune system of the patient. We don’t want to see any irregular shapes, we don’t want to see any large capsules or very small capsules, and we don’t want to see any islets that are partially coming through capsules. All of these things could break capsules and damage them, so we’re looking for very uniform perfect spherical capsules and ideally one islet close to the middle.
