Immunofluorescence Guide

Immunofluorescence (IF) is a common morphological approach used to determine the distribution of subcellular components. Antibodies that conjugated with fluorescent dyes are required in IF assay. The antibody specifically recognizes the antigen by binding to the epitope of target, and the fluorophore will be detected under a fluorescent microscope. Hence, subcellular components can be visualized in a dark background. IF can also be used as an alternative semiquantitative analysis method to monitoring the expression of the interest.
