Determination of Cell Density in Bacterial Cultures Using the Hellma Fiber Optic Probe in Combination with the Eppendorf Biospectrometer
2 Sept 2014Photometric measurement of turbidity for the purpose of determining cell density in a bacterial suspension is a basic method in every molecular biology laboratory. This application note demonstrates the use of a fiber optic probe in combination with the Eppendorf BioSpectrometer, which yields comparable results and thus presents a good alternative to a common measurement method.

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.
