High Throughput Membrane Protein Crystallisation

Presentation

The High Throughput Membrane Protein (HTMPC) platform fused with HTX Lab (EMBL) to give rise to a unique membrane protein crystallization platform. The platform is fully equipped to accomplish successful crystallization of your membrane protein (in meso, bicelle, vapor diffusion). Robotic systems nanovolume dispenser (Mosquito TTPLabtech) allows to screen 96 precipitant conditions with small amount of sample (5-10 µl per plate) in less than 10 minutes. Our platform works with commercially available kits specialized in membrane protein crystallization. An automated imaging system, RockImager 1500 (Formulatrix), visualizes crystallization drops with visible, polarized and UV lights, which allows a better identification of protein crystals. The smallest crystals which can be confidently detected are about 10 micrometers.

The diffusion rate and mobile fraction of the membrane protein can be determined by FRAP (Formulatrix), that allows to identify the optimal conditions for LCP crystal growth.
