In this article, we will consider how agarose gel electrophoresis works, how it can be interpreted and some of its purposes. Electrophoresis is a technique that uses electrical current to separate DNA ...

Investigators often work with complex nucleic acid samples in procedures such as amplification, renaturation, cDNA synthesis and normalization, sonication, digestion, nicking, labeling and ...

Figure 1: Titration of a 214-bp lac promoter DNA fragment with Escherichia coli CAP protein. Footprinting assays require simultaneous optimization of binding by the protein(s) of interest and the ...

Since the 18th-century researchers have studied proteins 1, but a number of discoveries in the 1960s that demonstrated sodium dodecyl sulfate (SDS) could facilitate the separation of proteins, ushered ...

Micellar electrokinetic chromatography is a modified version of capillary electrophoresis which is used to separate a wide range of molecules, from inorganic ions to large biopolymers. Electrophoresis ...
