The original interface between capillary zone electrophoresis and mass spectrometry was developed in 1987 [9] by Richard D. Smith and coworkers at Pacific Northwest National Laboratory, and who also later were involved in development of interfaces with other CE variants, including capillary isotachophoresis and capillary isoelectric focusing.
Capillary electrophoresis (CE) is a family of electrokinetic separation methods performed in submillimeter diameter capillaries and in micro- and nanofluidic channels.Very often, CE refers to capillary zone electrophoresis (CZE), but other electrophoretic techniques including capillary gel electrophoresis (CGE), capillary isoelectric focusing (CIEF), capillary isotachophoresis and micellar ...
[1] [2] Capillary electrochromatography is a combination of two analytical techniques, high-performance liquid chromatography and capillary electrophoresis. Capillary electrophoresis aims to separate analytes on the basis of their mass-to-charge ratio by passing a high voltage across ends of a capillary tube , which is filled with the analyte.
Electrophoresis is a laboratory technique in which the blood serum (the fluid portion of the blood after the blood has clotted) is applied to either an acetate membrane soaked in a liquid buffer, [3] or to a buffered agarose gel matrix, or into liquid in a capillary tube, and exposed to an electric current to separate the serum protein ...
The apparatus consists of a vial with a conical bottom, a grounded platinum electrode, a capillary to inject the aqueous solution, and an adjustable gold anode with a circular bottom that contacts the entire organic phase. EE is also often performed in a capillary electrophoresis capillary. This is referred to as capillary electroextraction, or ...
Different KCE methods are designed by varying initial and boundary conditions – the way interacting molecules enter and exit the capillary. Several KCE methods were described: non-equilibrium capillary electrophoresis of the equilibrium mixtures (NECEEM), [ 2 ] sweeping capillary electrophoresis (SweepCE), [ 3 ] and plug-plug KCE (ppKCE).
The PCR products are quantified, typically by (capillary) electrophoresis. Each probe pair consists of two oligonucleotides, with sequence that recognizes adjacent sites of the target DNA, a PCR priming site, and optionally a "stuffer" to give the PCR product a unique length when compared to other probe pairs in the MLPA assay.
SCIEX was founded in 1974 [1] by Canadian scientists Barry French, [2] Neil Reid, Adele Buckley, and businessman William Breukelman, to develop a mass spectrometer system based on atmospheric pressure ionisation and direct air sampling. In 1981, SCIEX was acquired by MDS Inc., a Canadian medical services and equipment company. [3]
