LCP is a liquid crystalline phase that forms spontaneously after mixing lipids and water, providing an ideal environment for membrane proteins. The continuous bilayer structure formed by LCP is similar to cell membranes, thus stabilizing proteins and promoting their crystallization.

Note: Users must provide their own consumables. This equipment only provides instrument operation assistance.


Crystal Imaging System & Diffractometer


Rock Imager®

Chameleon® delivers optimized grid vitrification of biological sample for cryo-electron microscopy (cryo-EM) by combining next-generation automation, blotless grid technology, and high speed plunging. Its core functions include rapid vitrification and automated sample handling, reducing manual operation errors and improving the reproducibility and efficiency of preparation. Through an automated nozzle, samples are precisely sprayed onto specialized grids, and the self-wicking property quickly forms a thin film, effectively solving issues such as the air-water interface and preferred orientation.
