Exosome-Depleted Fetal Bovine Serum Using Beckman Coulter Centrifugation
Exosome-Depleted Fetal Bovine Serum Using Beckman Coulter Centrifugation
23 Feb 2016Exosomes are small microvesicles released by all cell types, and proven to be involved in cancer metastasis. Exosome characterization and analysis comprise a fast, evolving research area even though their biological function has yet to be completely elucidated. In cell culture, fetal bovine serum (FBS) is usually incorporated into media, despite FBS containing extremely high levels of innate bovine extracellular vesicles which complicate downstream analyses. This application note explains the process for “home-brewing” exosome-depleted FBS by ultracentrifugation and compares the cell viability and media depletion percentage from two separate cell lines after treatment with different media types.

Cell / Tissue CultureCell culture or tissue culture is used to study the biology of cells or tissues and to isolate cellular products in an environment which can be manipulated and well defined. Accurately control your culture environment with bioreactors or culture incubators, bind your cells to a surface or together with an extracellular matrix. Distinguish cell types with differential media or proliferate cells with certain characteristics using selective media. Enrich your media with supplements such as growth factors, sera and vitamins.

This can reveal information on cell health (apoptosis, cytotoxicity, viability and proliferation assays), cell metabolism, cell migration and cell signaling mechanisms. Find the best cell-based assay products, kits and equipment with our peer reviewed product directory: compare products, check customer reviews and receiving pricing direct from manufacturers.Bioprocessing / FermentationBioprocessing is the use of biological materials to perform commercial, scientific or medical research processes. Biological materials used include cells, enzymes and organisms. Usually bioprocessing requires a batch or continuous bioreactor such as a fermentor or cell culture system. The advantages of using a reactor include high productivity, easy configuration, adjustable values and automation.Cell ViabilityCell viability assays assess the health of cells and their ability to proliferate. These tests are crucial in drug development, toxicity testing, and cell-based research. Common methods for assessing viability include MTT, live/dead assays, and flow cytometry. Browse our peer-reviewed product directory to find the best tools for cell viability assays, compare products, check reviews, and get pricing directly from manufacturers.BioprocessingBioprocessing is the use of biological systems for the conversion of raw materials to desired products. This includes the research, development and manufacturing stages of production and can refer to food processing, small-molecule pharmaceutical manufacture, production of recombinant protein therapeutics, or the generation of renewable energy.Cell GrowthCell growth refers to the process by which cells increase in size and number. It is essential for tissue development, wound healing, and cancer research. Understanding and controlling cell growth is a fundamental part of cell biology and regenerative medicine.
