Visão Geral da Separação e Isolamento de Células
Visão Geral da Separação e Isolamento 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, ...
Cultura Celular
Cultura 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 ...
Linhas Celulares
Linhas 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 ...
Tecnologia de Hibridoma
Tecnologia de Hibridoma
Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or ...
Homogeneização de Tecidos e Lise Celular
Homogeneização de Tecidos e Lise Celular
Tissue homogenization involves disintegrating tissue architecture and lysing cells, and is an early step in isolating and analyzing cellular components. ...
Fracionamento Subcelular
Fracionamento Subcelular
The homogenate obtained after cell lysis contains various membrane-bound organelles that can be further separated into pure fractions by subcellular ...
Citometria de Fluxo
Citometria de Fluxo
The development of flow cytometry techniques began in 1934 with initial attempts by Andrew Moldavan, a bacteriologist who counted the cells in a flowing ...
Princípios da Cromatografia em Coluna
Princípios da Cromatografia em Coluna
The chromatography technique was first invented in 1901 by Michael S. Tswett, a Russian botanist, to separate plant pigments using organic solvents. ...
Tipos de Cromatografia em Coluna
Tipos de Cromatografia em Coluna
The stability and compatibility of column material with samples are crucial for efficient purification in chromatographic techniques. Various operating ...
Imunoprecipitação
Imunoprecipitação
Immunoprecipitation, or IP, is a widely used technique that employs protein-antibody interactions to isolate proteins or protein complexes in their native ...
Proteínas de Marcação e Fusão
Proteínas de Marcação e Fusão
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 ...
Eletroforese em Gel Bidimensional
Eletroforese em Gel Bidimensional
Two-dimensional gel electrophoresis is a high-resolution protein separation method first introduced by O' Farrell and Klose in 1975. This method ...
Ensaio de Imunoabsorção Enzimática (ELISA)
Ensaio de Imunoabsorção Enzimática (ELISA)
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 ...
Espectrometria de Massa MALDI-TOF
Espectrometria de Massa MALDI-TOF
Mass spectrometry is a powerful characterization technique that can identify and separate a wide variety of compounds ranging from chemical to biological ...
Identificação de Peptídeos Usando Espectrometria de Massa em Tandem
Identificação de Peptídeos Usando Espectrometria de Massa em 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 ...
Difração de Raios X de Amostras Biológicas
Difração de Raios X de Amostras 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, ...
Aplicações da RMN na Biologia
Aplicações da RMN na Biologia
Nuclear magnetic resonance (NMR) spectroscopy is a very valuable analytical technique for researchers. It has been used for more than 50 years as an ...
Proteômica
Proteômica
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, ...
