3D-Electron Microscopy

 
Electron microscopy (EM) revolutionized biological research by providing high resolution micrographs of cellular ultrastructure and their interactions with other cells. Conventional 2D-EM has substantial limitations and manual serial sectioning approaches (to achieve 3D in EM resolution) are labor intensive which constrains its utility. With recent advances in technology and methods we make 3D-EM routinely possible.

We offer a complete range of automated EM imaging services and customizable analysis for biological research and drug development. Utilizing a technique called serial block-face scanning electron microscopy (SBFSEM) we generate a cost-effective, aligned stack of hundreds of serial sections overnight at nanoscale resolution.

Below is a brief comparison of our EM imaging specifications to other imaging technologies:
