Technology
Technique of electron microscopy in which the specimen is coated with heavy metal and then scanned by an electron beam. The resolution is not as great as with transmission electron microscopy, but preparation is easier (often by fixation followed by critical point drying), the depth of focus is relatively enormous, the surface of a specimen can be seen (though not the interior unless the specimen is cracked open) and the image is aesthetically pleasing.

Technology
A method for collecting tandem mass spectrometry data where an ion of a particular mass is selected in the first stage and a fragmented ion product is selected in the second mass spectrometer stage for detection. Selected reaction monitoring (SRM)-based experiments are generally performed in a triple quadrupole (QqQ) mass spectrometer.
Technology
The process of arranging protein, DNA or RNA sequences to identify regions with similar sequences that may elucidate functional, structural, or evolutionary relationships between the sequences.
Technology
Silver Staining or GMS staining is a technique for demonstrating fungi in tissue sections. It is primarily based on staining the polysaccharides in fungal cell wall (From BioGenex).
Technology
A rapid, simple, visual and sensitive technique for measuring DNA breakage in individual mammalian cells in response to a test agent. A cell is immobilized in agarose and made permeable and the broken DNA migrates out under the influence of the electric field. A damaged cell has the appearance of a comet with a brightly fluorescent cell body and a tail whose length and fluorescence intensity are related to the number of DNA-strand breaks induced by the test agent.
Technology
A procedure that can determine the nucleotide sequence for all of the RNA transcripts in an amplified nucleotide sample that was derived from a single cell.
Technology
Sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis is a procedure for estimating molecular weights of polypeptides, and uses SDS, a detergent that dissociates and unfolds oligomeric proteins into its subunits. The SDS binds to the polypeptides to form complexes with fairly constant charge to mass ratios. The electrophoretic migration rate through a gel is therefore determined only by the size of the complexes.
Technology
A technique for the detection of specific DNA fragments that have been separated by polyacrylamide-gel electrophoresis, transferred to a nitrocellulose or other type of paper or nylon membrane, and detected by hybridization and visualization with a labeled probe.
Technology
A novel karyotyping procedure which is based on the simultaneous hybridization of 24 chromosome-specific painting probes labeled with different fluorochromes or fluorochrome combinations. The measurement of defined emission spectra by means of interferometer-based spectral imaging allows for the definitive discernment of all human chromosomes in different colors. (from Schrock et al., Hum Genet 1997:101:255-62)
Technology
A laboratory test that produces a quantitative measurement of the reflection or transmission properties of a material as a function of wavelength.
