摘要: ABSTRACT To date, separation on the basis of surface net charge differences by electrofocusing has led to loss cell viability. Potentially, application following new approaches may allow for “charge separation” viable cells: a) Replacement Ampholine ordinary buffers as carrier constituents. b) strong acid and base anolyte catholyte aminoacids or buffers. Thus, flat pH gradients be generated tailored suit specific fractionation, either choice constituents, selective constituent displacement through anolytes catholytes. c) Electrofocusing at high ionic strength. d) Disaggregation amphoteric detergents capable maintaining native conformations biological activities. e) For preparative purposes, zone mobilization in achieved change anolyte, “cascade stacking.” Alternatively, material from isoelectric zones can recovered steady-state stacking. The present assumption that gel electrophoresis, based size shape among species, is ruled out our inability make gels with large enough pore sizes invalid. 30–50% Bis-crosslinked polyacrylamide gels, low percent agarose Pevikon viscous solutions linear an anticonvectant medium seem worth testing cells 1 regard their capability providing “size fractionation.” Proper design provides solvents suppressing aggregation while structures functions. Regulated concentration within starting use multiphasic buffer systems any chosen pH.
