Staining of molecules such as proteins and glycoconjugates allows for an analysis of their localization within the cell and provides insight into their functional status. Glycosyltransferases, a class of enzymes which are responsible for glycosylating host proteins, are mostly localized to the Golgi apparatus, and their localization is maintained in part by a protein vesicular tethering complex, the conserved oligomeric Golgi (COG) complex. Here we detail a combination of fluorescent lectin and immuno-staining in cells depleted of COG complex subunits to examine the status of Golgi glycosyltransferases. The combination of these techniques allows for a detailed characterization of the changes in function and localization of Golgi glycosyltransferases with respect to transient COG subunit depletion. © Springer Science+Business Media New York 2013.
