Technology
A high-resolution method used to isolate cells from their surrounding tissues, with the aid of a laser beam, under direct microscopic visualization. Specific cells can be isolated directly by cutting target cells away from unwanted cells, to obtain enriched cell populations.
Technology
A laboratory method in which the tissue from a histology slide is dissected under a microscope to procure specific cells or cell populations.
Technology
An imaging technique that uses multiple photons to absorb infrared light, thereby minimizing phototoxicty and photobleaching, making it an ideal method for imaging living specimens, especially those involving deep tissue.
Technology
Detection and measurement of the resonant spectra of molecular species in a tissue or sample.
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
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 potency unit defined as a minimal dose of infectious material at which preparation causes cytopathic effects (changes in the morphology and metabolism of tissue culture cells, indicating cell death, due to suspected infection) in the 50% of the tissue culture-containing flasks inoculated with that dilution of infectious material in the product potency assay or pathogen activity assay.

Indicators
A measurement of the length of time that it takes for clotting to occur when activating reagents are added to a plasma specimen. The test is partial due to the absence of tissue factor (Factor III) from the reaction mixture.
