title: Analysis of recombinant human tumor necrosis factor beta by capillary electrophoresis.
abstract: Capillary electrophoresis was used for the analysis of recombinant human tumor necrosis factor beta (rhTNF-beta). Reproducible separation of the protein could be achieved in Polybrene-coated capillaries. Optimum conditions for separation were achieved with a pH 4.5 sodium acetate buffer. Besides Polybrene-coated capillaries, other commercially available column and column-coating reagents were also examined for the separation of rhTNF-beta. Capillary electrophoresis was found to be a potentially useful method for product analysis and process monitoring in recombinant-DNA technology.
