Alternative to 2D gel electrophoresis – OFFGEL electrophoresis combined with high-sensitivity on-chip protein detection
Two-dimensional gel electrophoresis (2D-GE) employs isoelectric focusing in the first dimension and a separation of the proteins according to their molecular weights in the second dimension. The gels are then commonly stained using silver stain to visualize the protein pattern. This is a tedious and time-consuming procedure. Here, we demonstrate a combination of two newly developed methods – OF...
متن کاملOn-chip native gel electrophoresis-based immunoassays for tetanus antibody and toxin.
By integrating photopolymerized cross-linked polyacrylamide gels within a microfluidic device, we have developed a microanalytical platform for performing electrophoresis-based immunoassays. The microfluidic immunoassays are performed by gel electrophoretic separation and quantitation of bound and unbound antibody or antigen. To retain biological activity of proteins and maintain intact immune ...
متن کاملGel Electrophoresis
Electrophoresis is the migration of charged particles or molecules in an electric field. This occurs when the substances are in aqueous solution. The speed of migration is dependent on the applied electric field strength and the charges of the molecules. Thus, differently charged molecules will form individual zones while they migrate. In order to keep diffusion of the zones to a minimum, elect...
متن کاملGel Electrophoresis
Electrophoresis is the main metod for separating large polyelectrolyte molecules, primarily used on DNA, in biochemistry and medicine research. An overwiev of the models of physical mechanisms that are behind this phenomena will be presented. The prominent role is taken by reptation mechanisms, by which large exible polyelectrolytes thread their way through the pores of the gel matrix. There a...
متن کاملGel Electrophoresis
The separation of polypeptides by electrophoresis allowed Arne Tiselius to describe protein fractions corresponding to albumin, -, -, and -globulins in serum with the Rrst published diagram of human serum protein electrophoresis in 1939. The number of fractions slowly expanded into electrophoretic subfractions identiRed as 1, 2, 1, 2, 1 and 2. The mobility characteristics of these fractions are...
