Biological Science Imaging Resource

We at the Biological Science Imaging Resource (BSIR) are dedicated to making state of the art transmission electron microscopy (TEM) and confocal microscopy available to everyone without multimillion dollar investments in instruments and facilities.  We offer affordable, state of the art, remote robotic TEM imaging using FEI’s Titan Krios™ operated by staff with decades of EM experience. Through the Appion automated data collection system, users can view data collected in real time via a web browser and direct BSIR staff during the data acquisition process. We offer laser scanning dual photon confocal imaging using Zeiss’s LSM 510 confocal microscope which is managed by the physics department.

Many instruments are operated with a user shared collective of knowledge.  Training and technical assistance is provided.  Usage fees help to defray operating expenses incurred by Florida State University. Major equipment purchases are funded through individual and multi-user grants.
