Microspheres were formed above the cloud point at 70°C. Dylight-488 (green) labeled microspheres were incubated above the cloud point for 45 minutes. Dylight-549 (red) labeled microspheres were incubated above the cloud point for 17 minutes. Dylight-633 (blue) labeled microspheres were incubated above the cloud point for 11 minutes. (a) Combined channels, (b) blue only, (c) green only, (d) red only.
