  1. Costs are calculated based on list prices of vendors and are given as “set-up cost” that is the up front investment to start bead fabrication and as “cost per ml” reflecting the steady state cost per batch. Cost per experiment assumes a consumption of 50 μl beads. This amount allows profiling of about 20,000 cells; bead consumption for fewer cells will be similar because of dead volumes.
