🧪 Attic Drug Discovery Lab: Pipetting, Serial Dilution, Hill / IC50 Curve, Plate Reader, Docking Screen and Liquid Handler

Run a 3D attic drug-discovery laboratory: dock a 12-compound library, make serial dilutions by hand or with a liquid-handling robot, read the plate, fit a 4-parameter Hill curve for IC50 and Z', count cell viability on a hemocytometer and nominate leads within time, budget and safety limits. Pipetting error, Cheng-Prusoff, binding free energy and counting statistics are checked against closed forms.
