isoelectric focusing การใช้

• Using a process called isoelectric focusing, the different forms can be separated.
• The first-dimension of 2D gel is isoelectric focusing ( IEF ).
• Separation of the proteins by isoelectric point is called isoelectric focusing ( IEF ).
• ATTR can be identified using isoelectric focusing which separates out mutated forms of transthyretin.
• New techniques like " capillary isoelectric focusing immunoassay " are able to detect them in a population higher than 95 %.
• The initial 1973 case is atypical, in that no indication of aldolase A structural abnormality was found in isoelectric focusing, heat stabilization, electrophoresis or enzyme kinetics.
• Isoelectric focusing is the first step in two-dimensional gel electrophoresis, in which proteins are first separated by their pI and then further separated by molecular weight through SDS-PAGE.
• The proteins may be separated by charge and / or size ( isoelectric focusing agarose electrophoresis is essentially size independent ), and the DNA and RNA fragments by length.
• After separation, an additional separation method may then be used, such as isoelectric focusing or SDS-PAGE . The gel will then be physically cut, and the protein complexes extracted from each portion separately.
• Conductivity gradients are prevalent in on-chip electrokinetic processes such as preconcentration methods ( e . g . field amplified sample stacking and isoelectric focusing ), multidimensional assays, and systems with poorly specified sample chemistry.
• As protein electrophoresis is imprecise, A1AT phenotype is analysed by isoelectric focusing ( IEF ) in the pH range 4.5-5.5, where the protein migrates in a gel according to its isoelectric point or charge in a pH gradient.
• Two methods of analysis are possible : ( a ) protein electrophoresis, a method of analyzing the composition of fluids, also known as " agarose gel electrophoresis / Coomassie Blue staining ", and ( b ) the combination of isoelectric focusing / silver staining.
