Abstract
A modern electron microscopic approach to the investigation of the structural organization of proteins and subcellular structures demands the use of molecular genetic techniques. The successful implementation of genetic techniques is closely tied to a reporter gene such as the green fluorescent protein (GFP). Although GFP has been widely used for light microscopy, it has many limitations for use in electron microscopy. In the search for a reporter gene for electron microscopy, interest in the use of horseradish peroxidase (HRP) DNA has recently increased, and several studies already have proven the feasibility of HRP expression in mammalian cells. Here, we describe a protocol that uses a HRP chimera to label the endoplasmic reticulum of HEK cells.
