# TUTORIAL: Micropatterning multiwell plates with PRIMO
This tutorial describes the full PLPP Gel and PEG-SVA multiwell plates micropatterning protocol using the PRIMO2 photopatterning system and the LEONARDO5 software, for high-throughput micropatterning of proteins.
– High-throughput chemical passivation of the multiwell plate on the bench
– PRIMO 2 objective calibration
– Use of the Multiwell plate micropatterning module of the new LEONARDO 5 software version
– Proteins incubation
– Fluorescent patterns visualization
