The advent of digital imaging has transformed Western blot detection. Here we outline how Western blotting has changed and review qualities to look for in a digital imager. Chemiluminescence and fluorescence When most people think of imaging their...

Multicolor detection is a powerful application of fluorescent Western blotting. Two or more proteins can be detected on one blot using antibodies labeled with different fluorophores (Figure 1). The ability to simultaneously assay multiple proteins...

Detecting in-gel fluorescence enables the analysis of protein gels immediately after electrophoresis without staining or Western blotting. Separation of proteins by electrophoresis is a cornerstone of protein analysis. After separation identificat...

Fluorescent Western blots are the gold standard for quantitative Westerns. They are ideal for detecting multiple proteins simultaneously (multi-plexing) allowing in-lane normalization and detection of your protein of interest and loading control a...

Chemiluminescent Westerns are popular assays for assessing protein expression. In this indirect detection method chemiluminescent substrates emit light when reacted with an antibody conjugated to an enzyme. The emitted light is captured and archiv...
