As technology progresses, proteomic studies can probe further into how cellular phenotypes shape protein expression profiles. These studies require powerful tools which can identify, isolate, and extract pure samples of the cell type that one is interested in, such as laser capture microdissection (LCM). However, proteomic studies can be restricted by the small amounts of tissue collected by techniques such as LCM. Often, entire samples can be consumed during Western blotting - leaving researchers with only a single data point!
Capillary-based immunoassays offer a solution, as they are capable of detecting and quantifying protein abundance from much smaller volumes with superior sensitivity. In addition, capillary-based immunoassay workflows take significantly less time than traditional Western blotting, and can even be fully automated!
