University of Utah, Department of Biology - Dr. Brian T. Bennett (Assistant Research Professor in the laboratory of Dr. Erik Jorgensen), in collaboration with Dr. Joerg Bewersdorf (Assistant Professor, Department of Cell Biology, Yale University), completed the assembly of a super-resolution FPALM, Biplane microscope.  This instrument is a counterpart to the recently completed system at The Jackson Laboratory. This version improves the user interface and operation through a unique adaptation of the Agilent/Till Photonics Imic microscope. Biplane microscopy provides three-dimensional sub-100nm resolution (~30X30X75nm) of thick samples without scanning. The method employs the dual plane detection system of Biplane microscopes to achieve super-resolution in the z-axis.  Biplane methodology is combined with fluorescent photoactivatable localization microscopy (FPALM) to enable 3D sub-diffraction resolution without scanning.
