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.

• Carrier for high resolution isoelectric focusing (IEF)
• Soluble in cold water and hot water
• Stored at 2 to 8 °C

Pharmalyte® broad range can be used directly for agarose, Ultrodex or polyacrylamide gels and form linear gradients. Pharmalyte narrow range are intervals for special dedicated applications in polyacrylamide gels.

Each interval contains numerous ampholytes with a high buffering capacity per pH unit. Pharmalytes® carrier ampholytes form an extremely stable linear pH gradient and exhibit even conductivity across the gel.
