Micropatterning of protein is a powerful technology to control the spatial organization of cells and their biochemical microenvironment. We have developed PRIMO: a contactless and maskless UV projection system to facilitate micropatterning experiments. However, a major drawback until recently was the long illumination time that prevented from using PRIMO for high content screening experiments and cell-based assays. Here we present a new photo-initiator (PLPP Gel) and protocol allowing fast micropatterning of protein inside standard 96 well plates.
We are proud to collaborate with Leica Microsystems to ensure you obtain the best cell samples for cryo-ET! PRIMO micropatterning + Leica cryo-CLEM = Advanced workflow for whole cell cryo-ET
