Laboratory Exercises Assessment of the Purification of a Protein by Ion Exchange and Gel Permeation Chromatography
A 3-week group laboratory project experiment that involves the partial purification of myoglobin (Mb) from bovine hamburger is described. The experiment compares alternate purification methods (gel filtration and ion exchange chromatography) as to both overall yield and enhancement in relative purity. The purity and molecular weight of purified Mb is established by SDS-PAGE. Group reports are d...
متن کاملDevelopment of a new method based on chiral ligand-exchange chromatography for the enantioseparation of propranolol
A new chromatographic procedure was proposed for the separation of propranolol (PRN) enantiomers based upon enantioselective chiral ligand-exchange chromatography. The separation was carried out on a short C8 column leading to considerably short separation time. L-alanine and Cu2+ were applied as chiral selector and central bivalent complexing ion, respectively. It was found that the kind of co...

متن کاملArginine as an effective additive in gel permeation chromatography.
A major problem in gel permeation chromatography (GPC) or size exclusion chromatography is non-specific binding of applied proteins to the column matrix (stationary phase). We have tested an aqueous arginine solution as the GPC mobile phase on silica-based and polymer-based columns, using mouse monoclonal antibody and recombinant human activin, interleukin-6, basic fibroblast growth factor, and...
متن کاملPurification of cDNA for cloning using high performance gel permeation chromatography.
The use of HPLC in the separation of DNA fragments is well established (1). We have adapted these techniques to the separation of cDNA from linker sequences present during lambda cloning. Short linker sequences containing an EcoRl restriction site are coupled to blunt ended cDNA, excess linkers are cleaved using EcoRl. The efficiency of cloning into the lambda EcoRl site is improved by the remo...
