Continuous preparative gel electrophoresis.
Electrophoresis is widely used as a separative technique, particularly in protein chemistry. In some respects gelatinous media have an advantage over others as support media for electrophoresis, perhaps most obviously when a gel matrix of molecular dimensions is employed, allowing the simultaneous use of two properties for separation of the particles of interest-size and surface charge density....
متن کاملA new apparatus for preparative gel electrophoresis.
paratus is the dimension of the elution cham ber; if a large chamber is employed, dilution of solute occurs thus resulting in broadening of the elution patterns, while with a narrow chamber elution is frequently interrupted by the swelling of gel during operation. In many cases, either upward or downward elution has been employed and this leads to com plication of the apparatus. This communi ca...
متن کاملPurification of horse serum cholinesterase by preparative polyacrylamide gel electrophoresis.
Preparative polyacrylamide gel electrophoresis has been used in the final stages of purification to prepare horse serum cholinesterase which was at least 9.5% pure, as judged by analytical polyacrylamide gel electrophoresis. The starting material, already purified about 109-fold by the Strelitz method, was purified an additional 89-fold by the procedure. The method involved Sephadex G-ZOO and S...
متن کاملPreparative polyacrylamide gel electrophoresis purification of Clostridium perfringens enterotoxin.
Preparative polyacrylamide gel electrophoresis has been used to purify the enterotoxin of Clostridium perfringens from Sephadex G-100 extracts. Purified toxin of high specific activity was eluted in 1 to 3 h, depending upon the length of the acrylamide gel used. Recovery of biological activity with this technique ranged from 80 to 90%. The purity and physical characteristics of the toxin were s...
متن کاملProtection of DNA during preparative agarose gel electrophoresis against damage induced by ultraviolet light.
Preparative gel electrophoresis of double-stranded DNA usually includes staining the gel with ethidium bromide followed by illumination with ultraviolet (UV-B) light. In this report, DNA isolated from agarose gels was found to be a poor substrate for in vitro transcription, transformation of E. coli and PCR. Inhibition was not caused by enzyme-inhibiting impurities in the agarose gel, but was i...
