Technology
Technologies that facilitate the rapid determination of the nucleotide sequence of large numbers of strands or segments of DNA or RNA.
Technology
A technique that determines the nucleotide sequence of a pre-specified region of DNA or RNA by using primers that are specific for that region.
Technology
A common molecular biology procedure for detection of RNA molecules. RNA extracted from a sample was denatured and separated by slab gel electrophoresis, then blotted on to a nitrocellulose or nylon sheet and hybridized with labeled DNA or RNA that is complementary to the desired RNA, whose presence is subsequently indicated by autoradiography or other visualization techniques.
Technology
Detection and measurement of the resonant spectra of molecular species in a tissue or sample.
Technology
Measuring the optical density of a substance by shining light on it and measuring its transmission.
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. Parallel reaction monitoring (PRM)-based experiments are generally performed in a high-resolution hybrid quadrupole-Orbitrap (Q-OT) or time-of-flight mass spectrometer.
Technology
This is an all-round useful stain for many things, including glycogen, mucin, mucoprotein, glycoprotein, as well as fungi. The reaction is based on the oxidation of glycol group to aldehydes by periodate. The schiff's reagent selectively stains the aldehydes to a rose pink color. PAS is useful for outlining tissue structures--basement membranes, capsules, blood vessels, etc.
Technology
A type of spectroscopy that utilizes a laser beam to irradiate a sample containing particles in suspension, resulting in light scattering. Rapid fluctuations in scattering intensity, around a mean value at a certain angle, occur because of particle diffusion and are dependent upon on particle size. The calculated correlation function yields a diffusion coefficient, for a given temperature and viscosity, which can be used to calculate particle size.
Technology
A serological test that measures the ability of antibodies in specific concentrations of serum to prevent the formation of plaques in a cell monolayer when combined with a viral suspension.
Technology
An assay performed to assess platelet clumping, often with the addition of agonists.
Technology
Analytical and separative procedures in which molecules, particularly proteins or nucleic acids, are separated by their different electrophoretic mobilities in a hydrated gel. The gel suppresses convective mixing of the fluid phase through which the electrophoresis takes place and contributes molecular sieving. For proteins, commonly carried out in the presence of the anionic detergent sodium dodecylsulphate (SDS). SDS denatures proteins so that noncovalently associating sub unit polypeptides migrate independently and by binding to the proteins confers a net negative charge roughly proportional to the chain weight.
Technology
A method for amplifying a DNA base sequence using multiple rounds of heat denaturation of the DNA and annealing of oligonucleotide primers complementary to flanking regions in the presence of a heat-stable polymerase. This results in duplication of the targeted DNA region. Newly synthesized DNA strands can subsequently serve as additional templates for the same primer sequences, so that successive rounds of primer annealing, strand elongation, and dissociation produce rapid and highly specific amplification of the desired sequence. PCR also can be used to detect the existence of the defined sequence in a DNA sample.
