The advent of the Internet has allowed the development of remote access capabilities to a growing variety of microscopy systems. The Materials MicroCharacterization Collaboratory, for example, has developed an impressive facility that provides remote access to a number of highly sophisticated microscopy and microanalysis instruments. While certain types of microscopes, such as scanning electron microscopes, transmission electron microscopes, scanning probe microscopes, and others have already been established for telepresence microscopy, no one has yet reported on the development of similar capabilities for the confocal laser scanning microscope.At California State University-Stanislaus, home of the CSUPERB (California State University Program for Education and Research in Biotechnology) Confocal Microscope Core Facility, we have established a remote access confocal laser scanning microscope facility that allows users with virtually any type of computer platform to connect to our system. Our Leica TCS NT confocal system, with an interchangeable upright (DMRXE) and inverted microscope (DMIRBE) set up,

Light microscopic techniques for visualizing biomolecules and biochemical processes in situ have become indispensable in studies concerning the structural organization of supramolecular assemblies in cells and of processes during the cell cycle, transformation, differentiation, and development. Confocal laser scanning microscopy offers a number of advantages for the in situ localization and quantitation of fluorescence labeled targets and probes: (i) rejection of interfering signals emanating from out-of-focus and adjacent structures, allowing the “optical sectioning” of the specimen and 3-D reconstruction without time consuming deconvolution; (ii) increased spatial resolution; (iii) electronic control of contrast and magnification; (iv) simultanous imaging of the specimen by optical phenomena based on incident, scattered, emitted, and transmitted light; and (v) simultanous use of different fluorescent probes and types of detectors.We currently use a confocal laser scanning microscope CLSM (Zeiss, Oberkochen) equipped with 3-laser excitation (u.v - visible) and confocal optics in the fluorescence mode, as well as a computer-controlled X-Y-Z scanning stage with 0.1 μ resolution.

In this paper we describe the modifications necessary to upgrade, at affordable cost, a commercially available confocal laser scanning microscope for use with ultraviolet (UV) excitation. The optical problems associated with these modifications are described in detail, and easy solutions to solve them are suggested. The optical resolution of the instrument was tested with fluorescent beads and was found to be close to diffraction limited. The light losses due to lateral chromatic aberration were assessed in a thick fluorescent specimen and were found to be comparable to those usually observed with visible light. For a more visual example of the resolution of this instrument, isolated ventricular heart muscle cells were loaded with the fluorescent Ca2+ indicator indo 1. This allowed us to visualize subcellular structural detail and to illustrate the optical sectioning capability of the UV confocal microscope when recording indo 1 emission. Dual-emission line scans were used to perform ratiometric time-resolved detection of Ca2+ transients in voltage-clamped heart muscle cells loaded with the salt form of indo 1. The system presented in this paper should significantly broaden the range of fluorescent indicators that can be used in confocal microscopy.
