What % sensors are active on the current generation of chips, and what % are occupied with beads. I thought they were still dependent on poisson distribution, so loading at < 30% of total sites.

Also- what are the implications for pixel (and bead size) with the Proton chips?
The chip looks to be about 15mm by 2mm (unless those are giant or midget hands), or 15000um x 20000um, giving a total area of 3x 10^8 um2. 170x 10^6 active sites implies only ~2um2 per pixel. This, in turn suggests feature sizes of no more than .5um2 (allowing for spacing between features).

It seems possible that this is now no longer going to be a bead-based platform...but with beads replaced by colonies, clusters or some such thing.
