Pharmalyte, broad range pH 3-10

Pharmalyte carrier ampholytes, prepared by the co-polymerization of glycine, glycylglycine, amines, and epichlorohydrin, are available in five broad-range and four narrow-range pH intervals. Each interval contains numerous ampholytes with a high buffering capacity per pH unit. Pharmalyte carrier ampholytes form an extremely stable linear pH gradient and exhibit even conductivity across the gel. For precast PhastGel gels for PhastSystem, see PhastGel.
