An evaluation of confocal versus conventional imaging of biological structures by fluorescence light microscopy.
TLDR
It is found that confocal imaging gives greatly enhanced images of biological structures viewed with epifluorescence, and the improvements are such that it is possible to optically section thick specimens with little degradation in the image quality of interior sections.Abstract:
Scanning confocal microscopes offer improved rejection of out-of-focus noise and greater resolution than conventional imaging. In such a microscope, the imaging and condenser lenses are identical and confocal. These two lenses are replaced by a single lens when epi-illumination is used, making confocal imaging particularly applicable to incident light microscopy. We describe the results we have obtained with a confocal system in which scanning is performed by moving the light beam, rather than the stage. This system is considerably faster than the scanned stage microscope and is easy to use. We have found that confocal imaging gives greatly enhanced images of biological structures viewed with epifluorescence. The improvements are such that it is possible to optically section thick specimens with little degradation in the image quality of interior sections.read more

Two-Photon Laser Scanning Fluorescence Microscopy
TL;DR: The fluorescence emission increased quadratically with the excitation intensity so that fluorescence and photo-bleaching were confined to the vicinity of the focal plane as expected for cooperative two-photon excitation.

Fluorescent indicators for cytosolic calcium based on rhodamine and fluorescein chromophores.
TL;DR: A new group of fluorescent indicators with visible excitation and emission wavelengths has been synthesized for measurements of cytosolic free Ca2+.

Very large scale immobilized polymer synthesis
TL;DR: In this paper, a method and apparatus for preparation of a substrate containing a plurality of sequences is described, where a set of photoremovable groups are attached to a surface of the substrate and selected regions of the surface are exposed to light so as to activate the selected areas.

Delineation of individual human chromosomes in metaphase and interphase cells by in situ suppression hybridization using recombinant DNA libraries
TL;DR: A method of in situ hybridization for visualizing individual human chromosomes from pter to qter, both in metaphase spreads and interphase nuclei, is reported and should be useful for both karyotypic studies and for the analysis of chromosome topography in interphase cells.

TL;DR: Through-scalp and through-skull fluorescence imaging of mouse cerebral vasculature without craniotomy is reported utilizing the intrinsic photoluminescence of single-walled carbon nanotubes in the 1.3–1.4 micrometre near-infrared window, providing real-time assessment of blood flow anomaly in a mouse middle cerebral artery occlusion stroke model.

Rat monoclonal antitubulin antibodies derived by using a new nonsecreting rat cell line.
TL;DR: The antitubulin antibodies in the serum of rats bearing two of the hybrid myeloma tumors gave titers of up to 1:10(6) from which large amounts of monoclonal antibodies could be easily purified and gave clear immunofluorescent staining of yeast mitotic spindles as well as the interphase microtubule network of tissue culture cells.

Fading of immunofluorescence during microscopy: a study of the phenomenon and its remedy
TL;DR: Study of the kinetics of this photo-bleaching performed by microfluorimetry and on FITC conjugate in solution and the effects of a range of additives incorporated in the mountant suggest that the fading is due to a destructive reaction with protein of the dye in its excited singlet state and that retarding additives suppress this.

Measurement of cytosolic free Ca2+ in individual small cells using fluorescence microscopy with dual excitation wavelengths.
TL;DR: Fura-2 as mentioned in this paper is a fluorescent Ca2+ indicator that can be used to estimate the ratio of Ca2-bound dye to free dye and hence cytosolic free Ca2+, which largely cancels out the effects of cell thickness, dye content, or instrumental efficiency.
