Analyzing Cells and Proteins

细胞分离和分离概述
细胞分离和分离概述
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, ...
细胞培养
细胞培养
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 ...
细胞系
细胞系
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 ...
杂交瘤技术
杂交瘤技术
Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or ...
组织匀浆和细胞裂解
组织匀浆和细胞裂解
Tissue homogenization involves disintegrating tissue architecture and lysing cells, and is an early step in isolating and analyzing cellular components. ...
亚细胞组分分离
亚细胞组分分离
The homogenate obtained after cell lysis contains various membrane-bound organelles that can be further separated into pure fractions by subcellular ...
流式细胞术
流式细胞术
The development of flow cytometry techniques began in 1934 with initial attempts by Andrew Moldavan, a bacteriologist who counted the cells in a flowing ...
柱色谱原理
柱色谱原理
The chromatography technique was first invented in 1901 by Michael S. Tswett, a Russian botanist, to separate plant pigments using organic solvents. ...

The stability and compatibility of column material with samples are crucial for efficient purification in chromatographic techniques. Various operating ...
免疫沉淀
免疫沉淀
Immunoprecipitation, or IP, is a widely used technique that employs protein-antibody interactions to isolate proteins or protein complexes in their native ...
标记和融合蛋白
标记和融合蛋白
Proteins are involved in several cellular processes and biochemical reactions. Analyzing a specific protein of interest requires it to be isolated from ...
SDS 页面

Gel electrophoresis is a method that separates biological macromolecules like nucleic acids or proteins by forcing them to pass through a gel matrix under ...
蛋白质印迹
蛋白质印迹
Western blotting is an analytical technique for protein identification. It has various applications in immunology and medicine, including detecting ...
二维凝胶电泳
二维凝胶电泳
Two-dimensional gel electrophoresis is a high-resolution protein separation method first introduced by O' Farrell and Klose in 1975. This method ...
酶联免疫吸附测定
酶联免疫吸附测定
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 质谱仪
MALDI-TOF 质谱仪
Mass spectrometry is a powerful characterization technique that can identify and separate a wide variety of compounds ranging from chemical to biological ...
使用串联质谱法进行肽鉴定
使用串联质谱法进行肽鉴定
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 ...
生物样品的 X 射线衍射
生物样品的 X 射线衍射
X-ray diffraction or XRD is an analytical tool that utilizes X-rays to study ordered structures such as crystalline organic and inorganic samples, ...
核磁共振在生物学中的应用
核磁共振在生物学中的应用
Nuclear magnetic resonance (NMR) spectroscopy is a very valuable analytical technique for researchers. It has been used for more than 50 years as an ...
蛋白质组学
蛋白质组学
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, ...
