“…The effects of variable conditions (e.g., pH, temperature, current intensity) upon sample behavior (266,1196,1199,2449), as well as factors affecting the homogeneity of voltage gradients (849,1198,1201) and solution movements within the bed (12,169,1197,1202,1203, 2440 have been investigated, as have the optimum conditions for polyacrylamide electrophoresis (24II), chromatographic phenomena (1200), protein adsorption on paper (1629), and gel filtration by starch (639). There are favorable reports of the effects of magnetic fields (1205, 1855) and of alternating current im-VOL.…”
