Analyzing Cells and Proteins

Overview Of Cell Separation And Isolation
Overview Of Cell Separation And Isolation
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, ...
Cell Culture
Cell Culture
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 ...
Cell Lines
Cell Lines
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 ...
Hybridoma Technology
Hybridoma Technology
Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or ...
Tissue Homogenization and Cell Lysis
Tissue Homogenization and Cell Lysis
Tissue homogenization involves disintegrating tissue architecture and lysing cells, and is an early step in isolating and analyzing cellular components. ...
Subcellular Fractionation
Subcellular Fractionation
The homogenate obtained after cell lysis contains various membrane-bound organelles that can be further separated into pure fractions by subcellular ...
Flow Cytometry
Flow Cytometry
The development of flow cytometry techniques began in 1934 with initial attempts by Andrew Moldavan, a bacteriologist who counted the cells in a flowing ...
Principles Of Column Chromatography
Principles Of Column Chromatography
The chromatography technique was first invented in 1901 by Michael S. Tswett, a Russian botanist, to separate plant pigments using organic solvents. ...
Types Of Column Chromatography
Types Of Column Chromatography
The stability and compatibility of column material with samples are crucial for efficient purification in chromatographic techniques. Various operating ...
Immunoprecipitation
Immunoprecipitation
Immunoprecipitation, or IP, is a widely used technique that employs protein-antibody interactions to isolate proteins or protein complexes in their native ...
Tagging and Fusion Proteins
Tagging and Fusion Proteins
Proteins are involved in several cellular processes and biochemical reactions. Analyzing a specific protein of interest requires it to be isolated from ...
SDS-PAGE
SDS-PAGE
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 ...
Two-dimensional Gel Electrophoresis
Two-dimensional Gel Electrophoresis
Two-dimensional gel electrophoresis is a high-resolution protein separation method first introduced by O' Farrell and Klose in 1975. This method ...
Enzyme-Linked Immunosorbent Assay
Enzyme-Linked Immunosorbent 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 Mass Spectrometry
MALDI-TOF Mass Spectrometry
Mass spectrometry is a powerful characterization technique that can identify and separate a wide variety of compounds ranging from chemical to biological ...
Peptide Identification Using Tandem Mass Spectrometry
Peptide Identification Using Tandem Mass Spectrometry
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 ...
X-ray Diffraction of Biological Samples
X-ray Diffraction of Biological Samples
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 Of NMR In Biology
Applications Of NMR In Biology
Nuclear magnetic resonance (NMR) spectroscopy is a very valuable analytical technique for researchers. It has been used for more than 50 years as an ...
Proteomics
Proteomics
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, ...
