Western blotting allows scientists to identify specific proteins ... they are separated by size. 2 A protein ladder containing a range of known molecular weights is included in one well to determine ...

A western blot is a laboratory method used to detect specific protein molecules from among a mixture of proteins. This mixture can include all of the proteins associated with a particular tissue ...

Assessing the relative change in protein expression is a valuable and versatile tool for a wide range of basic and applied research. Scientists routinely use quantitative western blots to investigate ...

The method by which protein researchers identify specific proteins in complex mixtures has changed little in 40 years. After sorting and tagging samples with a technique called western blotting ...
