Western blotting is a highly valued method for protein identification and relative quantitation in complex samples.It combines size-based electrophoretic separation with immunoaffinity to identify specific proteins.This technique remains popular and has become a workhorse in biochemical research and clinical laboratories.Despite its utility and popularity,this method has many limitations including slow analysis,incompatibility with limited sample application,low throughput and low information content.Recently there has been significant success in improving different aspects of Western blotting.In this review,we provide an overview of the developments in the area of improving conventional Western blotting methods with a focus on recent developments in microfluidic Western blotting.We overview different separation platforms,and discuss studies on protein transfer methods as well as protein immobilization methods and chemistries.We also describe integrated miniaturized platforms that can perform rapid separations and immunodetections.

This technique remains popular and has become a workhorse in biochemical research and clinical laboratories. Despite its utility and popularity, this method has many limitations including slow analysis, incompatibility with limited sample application, low throughput and low information content. Reallyly there has been significant success in improving different aspects of Western blotting. in this review, we provide an overview of the developments in the area of improving conventional Western blotting methods with a focus on recent developments in microfluidic Western blotting. We overview different separation platforms, and discuss studies on protein transfer methods as well as protein immobilization methods and chemistries. We also describe integrated miniaturized platforms that canperform rapid separations and immunodetections.
