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.
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 ...
The 3D Cell Culturing by Magnetic Levitation method (MLM) is the application of growing 3D tissue by inducing cells treated with magnetic nanoparticle assemblies in spatially varying magnetic fields using neodymium magnetic drivers and promoting cell to cell interactions by levitating the cells up to the air/liquid interface of a standard petri ...
This single cell shows the process of the central dogma of molecular biology, which are all steps researchers are interested to quantify (DNA, RNA, and Protein).. In cell biology, single-cell analysis and subcellular analysis [1] refer to the study of genomics, transcriptomics, proteomics, metabolomics, and cell–cell interactions at the level of an individual cell, as opposed to more ...
These labeled cell suspension is then put into a separation column in a strong magnetic field. The labeled cells are contained, magnetized, while in the magnetic field and the unlabeled cells are suspended, un-magnetized, to be collected. Once removed from magnetic field positive cells are eluted.
Primary isolate is a pure microbial or viral sample that has been obtained from an infected individual, rather than grown in a laboratory. In chemistry and bacteriology , the verb isolate means to obtain a pure chemical, bacteriological or viral sample.
Microbeads are used for cell isolation and cell expansion. Proteins and protein complexes can be separated; e.g., in immunoprecipitation protocols. Molecular studies and diagnostics also benefit from microbeads (e.g. immunoassay IVD and nucleic acid IVD).
