Cryo-EM has developed into a powerful tool for studying the fine detail of biological structure required in areas such as drug discovery. Despite this, producing quality frozen grids with vitreous ice of an appropriate thickness and evenly distributed particles remains a key bottleneck in the structure determination workflow. We drew on decades of experience in structural biology process automation to create chameleon and provide optimizable vitrification for each unique sample behavior, reducing the time and costs associated with traditional trial-and-error methods.
chameleon streamlines cryo-EM sample preparation workflows with high speed blot-free vitrification, automated grid handling, and the ability to screen grids based on likely ice thickness. Guided workflows simplify set up, use, and cleaning of the instrument while the minimization of manual handling eliminates sample loss and damage.
The powerful combination of robotics, automation, and intelligent software allows experts and novice users alike quicker access to consistent results. Users can confidently work with the instrument using guided software protocols intended to handle the experimental framework and limit manual intervention.Explore chameleon
Self-wicking grids for use exclusively with chameleon
QUANTIFOIL Active grids are unique in being the first commercially produced grids with copper nano-wire covered bars to promote thin film formation through a process of “self-wicking”. This novel grid technology removes the variability of applying an externally applied filter paper to remove excess sample during blotting.Explore QUANTIFOIL® Active
