Study of early events during herpes simplex virus type 1 infection by confocal microscopy

Abstract

Laser scanning confocal microscopy is a powerful technique that can be applied to study the localisation and behaviour of proteins and nucleic acids in many experimental situations. It is a particularly useful technique for the study of virus infections because of the changes that occur in the distribution and amounts of both viral and cellular proteins as infection develops. These changes reflect key stages and important regulatory events that govern the efficiency of infection. Using herpes simplex virus type 1 infected cells as an experimental model, this article provides guidance for users new to confocal microscopy on basic principles and techniques. The emphasis is on recognising, diagnosing and avoiding potential artifacts, and the workflow of the production of high quality, technically correct images.
