Primary cell culture is the ex vivo culture of cells freshly obtained from a multicellular organism, as opposed to the culture of immortalized cell lines.In general, primary cell cultures are considered more representative of in vivo tissues than cell lines, and this is recognized legally in some countries such as the UK (Human Tissue Act 2004).

Cell isolation is the process of separating individual living cells from a solid block of tissue or cell suspension. While some types of cell naturally exist in a separated form (for example blood cells ), other cell types that are found in solid tissue require specific techniques to separate them into individual cells.
Multiplex RNA visualization in cells using ViewRNA FISH Assays A metaphase cell positive for the bcr/abl rearrangement (associated with chronic myelogenous leukemia) using FISH. The chromosomes can be seen in blue. The chromosome that is labeled with green and red spots (upper left) is the one where the rearrangement is present.
Currently six primary isolation/collection technologies exist using a microscope and device for cell isolation. Four of these typically use an ultraviolet pulsed laser (355 nm) for the cutting of the tissues directly or the membranes/film, and sometimes in combination with an IR laser responsible for heating/melting a sticky polymer for ...

DNA extraction is the process of isolating DNA from the cells of an organism isolated from a sample, typically a biological sample such as blood, saliva, or tissue. It involves breaking open the cells, removing proteins and other contaminants, and purifying the DNA so that it is free of other cellular components.

It is often essential to isolate a pure culture of microorganisms. A pure (or axenic) culture is a population of cells or multicellular organisms growing in the absence of other species or types. A pure culture may originate from a single cell or single organism, in which case the cells are genetic clones of one another.
