Protocol describes a method for estimation of mammalian cell number in a defined volume of medium using a hemocytometer. Automated methods using cell-counting devices such as those produced by Coulter are desirable when large numbers of individual samples are to be counted. - [Read Estimation of Cell Number by Hemocytometry Counting Protocol]

In this protocol, extracts prepared from cells transfected with a chloramphenicol acetyltransferase (CAT) reporter plasmid are incubated with radiolabeled chloramphenicol. The acetylated products generated by the action of CAT are separated from the unmodified drug by thin-layer chromatography and quantitated by scraping the spots from the thin-layer plates and counting them by scintillation spectroscopy. - [Read Measurement of CAT in Extracts of Mammalian Cells Using Thin-layer Chromatography]

SAGE is a new method that has been invented at Johns Hopkins University in USA to give scientists an overview of a cell’s complete gene activity. It works by capturing RNAs, identifying them and counting them. By comparing different types of cells, the researchers hope to generate profiles that will help them understand healthy cells and what goes wrong during diseases. Includes: How SAGE works and Steps of SAGE. - [Read Serial Analysis Of Gene Expression (SAGE)]
