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 capillary electrophoresis mobility shift assay for protein-DNA binding affinities free in solution.
Quantitative determination of dissociation constants for DNA-protein complexes will help clarify the molecular mechanisms of transcription, replication and DNA repair. A practical capillary electrophoresis mobility shift assay (CEMSA) for protein-DNA affinities free in solution is presented. The method is fast and simple, precise and general. The speed (<2 min separations) and simplicity derive...
متن کاملMicroheterogeneity in purified broad bean polyphenol oxidase.
Polyphenoloxidase was purified from chloroplasts of broad bean leaves (Vicia faba L.) to apparent homogeneity. The enzyme was composed of two proteins with an apparent mass of 65 and 68 kilodaltons after sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The isolated enzyme contained covalently attached carbohydrates and bound concanavalin A, Phaseolus vulgaris erythroagglutinin, and Ri...
متن کاملجداسازی پروتئین LMG از بافت کبد موش و میانکنش آن با
ABSTRACT In eukaryote cells, DNA is complexed with a series of basic proteins making units of chromatin structure named nucleosomes. In addition, nonhistone proteins with different function are the components of chromatin. Among these proteins, a group with a low mobility on gel electrophoresis have been identified and named LMG. In this study a LMG protein with a molecular weigh of 160 ...
متن کاملA Simple Method of Preparative Electrophoresis.
A method of preparative electrophoresis is described. A volume of approximately 1 ml. of protein solution can be applied with the cell used. A “marker” solution, applied adjacent to the sample to be separated, indicates the positions of the protein bands during the migration. The procedure has the advantages of a high degree of recovery, simplicity of operation, and utilization of an electropho...
