Vue d’ensemble de la séparation et de l’isolement cellulaires
Vue d’ensemble de la séparation et de l’isolement cellulaires
Cell separation was first achieved in 1964 by S. H. Seal, who separated large tumor cells from the smaller blood cells using filtration. Two years later, ...
Culture cellulaire
Culture cellulaire
Most vertebrate cells grow in vitro attached to a substrate as a monolayer, called adherent cultures. The flasks and plates used to grow cells are ...
Lignées cellulaires
Lignées cellulaires
A cell line is a population of cells grown in vitro that can be subcultured over several generations. Normal cells cease to divide after a certain number ...
Technologie Hybridome
Technologie Hybridome
Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or ...
Homogénéisation tissulaire et lyse cellulaire
Homogénéisation tissulaire et lyse cellulaire
Tissue homogenization involves disintegrating tissue architecture and lysing cells, and is an early step in isolating and analyzing cellular components. ...
Fractionnement subcellulaire
Fractionnement subcellulaire
The homogenate obtained after cell lysis contains various membrane-bound organelles that can be further separated into pure fractions by subcellular ...
Cytométrie en flux
Cytométrie en flux
The development of flow cytometry techniques began in 1934 with initial attempts by Andrew Moldavan, a bacteriologist who counted the cells in a flowing ...
Principes de la chromatographie sur colonne
Principes de la chromatographie sur colonne
The chromatography technique was first invented in 1901 by Michael S. Tswett, a Russian botanist, to separate plant pigments using organic solvents. ...
Types de chromatographie sur colonne
Types de chromatographie sur colonne
The stability and compatibility of column material with samples are crucial for efficient purification in chromatographic techniques. Various operating ...
Immunoprécipitation
Immunoprécipitation
Immunoprecipitation, or IP, is a widely used technique that employs protein-antibody interactions to isolate proteins or protein complexes in their native ...
Marquage et protéines de fusion
Marquage et protéines de fusion
Proteins are involved in several cellular processes and biochemical reactions. Analyzing a specific protein of interest requires it to be isolated from ...

Western blotting is an analytical technique for protein identification. It has various applications in immunology and medicine, including detecting ...
Électrophorèse sur gel bidimensionnelle
Électrophorèse sur gel bidimensionnelle
Two-dimensional gel electrophoresis is a high-resolution protein separation method first introduced by O' Farrell and Klose in 1975. This method ...
Dosage immuno-enzymatique
Dosage immuno-enzymatique
In 1971, Peter Perlman and Eva Engvall developed an Enzyme-linked immunosorbent assay (ELISA or EIA). ELISA differs from western blot in that the assays ...
Spectrométrie de masse MALDI-TOF
Spectrométrie de masse MALDI-TOF
Mass spectrometry is a powerful characterization technique that can identify and separate a wide variety of compounds ranging from chemical to biological ...
Identification de peptides à l’aide de la spectrométrie de masse en tandem
Identification de peptides à l’aide de la spectrométrie de masse en tandem
Tandem mass spectrometry, also known as MS/MS or MS2, is an analytical technique that employs two mass analyzers. Essentially it is a series of mass ...
Diffraction des rayons X d’échantillons biologiques
Diffraction des rayons X d’échantillons biologiques
X-ray diffraction or XRD is an analytical tool that utilizes X-rays to study ordered structures such as crystalline organic and inorganic samples, ...
Applications de la RMN en biologie
Applications de la RMN en biologie
Nuclear magnetic resonance (NMR) spectroscopy is a very valuable analytical technique for researchers. It has been used for more than 50 years as an ...
Protéomique
