Descripción general de la separación y el aislamiento de células
Descripción general de la separación y el aislamiento de células
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, ...
Cultivo celular
Cultivo celular
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 ...
Líneas celulares
Líneas celulares
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 ...
Tecnología de hibridoma
Tecnología de hibridoma
Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or ...
Homogeneización de tejidos y lisis celular
Homogeneización de tejidos y lisis celular
Tissue homogenization involves disintegrating tissue architecture and lysing cells, and is an early step in isolating and analyzing cellular components. ...
Fraccionamiento subcelular
Fraccionamiento subcelular
The homogenate obtained after cell lysis contains various membrane-bound organelles that can be further separated into pure fractions by subcellular ...
Citometría de flujo
Citometría de flujo
The development of flow cytometry techniques began in 1934 with initial attempts by Andrew Moldavan, a bacteriologist who counted the cells in a flowing ...
Principios de la cromatografía en columna
Principios de la cromatografía en columna
The chromatography technique was first invented in 1901 by Michael S. Tswett, a Russian botanist, to separate plant pigments using organic solvents. ...
Tipos de cromatografía en columna
Tipos de cromatografía en columna
The stability and compatibility of column material with samples are crucial for efficient purification in chromatographic techniques. Various operating ...
Inmunoprecipitación
Inmunoprecipitación
Immunoprecipitation, or IP, is a widely used technique that employs protein-antibody interactions to isolate proteins or protein complexes in their native ...
Marcaje y fusión de proteínas
Marcaje y fusión de proteínas
Proteins are involved in several cellular processes and biochemical reactions. Analyzing a specific protein of interest requires it to be isolated from ...
SDS-PÁGINA
SDS-PÁGINA
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 ...
Electroforesis en gel bidimensional
Electroforesis en gel bidimensional
Two-dimensional gel electrophoresis is a high-resolution protein separation method first introduced by O' Farrell and Klose in 1975. This method ...
Ensayo de inmunoabsorción enzimática
Ensayo de inmunoabsorción enzimática
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 ...
Espectrometría de masas MALDI-TOF
Espectrometría de masas MALDI-TOF
Mass spectrometry is a powerful characterization technique that can identify and separate a wide variety of compounds ranging from chemical to biological ...
Identificación de péptidos mediante espectrometría de masas en tándem
Identificación de péptidos mediante espectrometría de masas en tándem
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 ...
Difracción de rayos X de muestras biológicas
Difracción de rayos X de muestras biológicas
X-ray diffraction or XRD is an analytical tool that utilizes X-rays to study ordered structures such as crystalline organic and inorganic samples, ...
Aplicaciones de la RMN en biología
Aplicaciones de la RMN en biología
Nuclear magnetic resonance (NMR) spectroscopy is a very valuable analytical technique for researchers. It has been used for more than 50 years as an ...
Proteómica
Proteómica
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, ...
