Überblick über die Zellseparation und -isolierung
Überblick über die Zellseparation und -isolierung
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, ...
Zellkultur
Zellkultur
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 ...
Zelllinien
Zelllinien
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 ...
Hybridomatechnik
Hybridomatechnik
Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or ...
Gewebe Homogenisierung und Zelllyse
Gewebe Homogenisierung und Zelllyse
Tissue homogenization involves disintegrating tissue architecture and lysing cells, and is an early step in isolating and analyzing cellular components. ...
Subzelluläre Fraktionierung
Subzelluläre Fraktionierung
The homogenate obtained after cell lysis contains various membrane-bound organelles that can be further separated into pure fractions by subcellular ...
Durchflusszytometrie
Durchflusszytometrie
The development of flow cytometry techniques began in 1934 with initial attempts by Andrew Moldavan, a bacteriologist who counted the cells in a flowing ...
Grundlagen der Säulenchromatographie
Grundlagen der Säulenchromatographie
The chromatography technique was first invented in 1901 by Michael S. Tswett, a Russian botanist, to separate plant pigments using organic solvents. ...
Arten der Säulenchromatographie
Arten der Säulenchromatographie
The stability and compatibility of column material with samples are crucial for efficient purification in chromatographic techniques. Various operating ...
Immunpräzipitation
Immunpräzipitation
Immunoprecipitation, or IP, is a widely used technique that employs protein-antibody interactions to isolate proteins or protein complexes in their native ...
Tagging und Fusionsproteine
Tagging und Fusionsproteine
Proteins are involved in several cellular processes and biochemical reactions. Analyzing a specific protein of interest requires it to be isolated from ...
SDB-SEITE
SDB-SEITE
Gel electrophoresis is a method that separates biological macromolecules like nucleic acids or proteins by forcing them to pass through a gel matrix under ...
Western-Blotting
Western-Blotting
Western blotting is an analytical technique for protein identification. It has various applications in immunology and medicine, including detecting ...
Zweidimensionale Gelelektrophorese
Zweidimensionale Gelelektrophorese
Two-dimensional gel electrophoresis is a high-resolution protein separation method first introduced by O' Farrell and Klose in 1975. This method ...
Enzymgebundener Immunsorbent-Assay
Enzymgebundener Immunsorbent-Assay
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 ...
MALDI-TOF-Massenspektrometrie
MALDI-TOF-Massenspektrometrie
Mass spectrometry is a powerful characterization technique that can identify and separate a wide variety of compounds ranging from chemical to biological ...
Identifizierung von Peptiden durch die Tandem-Massenspektrometrie
Identifizierung von Peptiden durch die Tandem-Massenspektrometrie
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 ...
Röntgendiffraktion biologischer Proben
Röntgendiffraktion biologischer Proben
X-ray diffraction or XRD is an analytical tool that utilizes X-rays to study ordered structures such as crystalline organic and inorganic samples, ...
Anwendungen der NMR in der Biologie
Anwendungen der NMR in der 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 ...
Proteomik
Proteomik
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, ...
