FEATURED PRODUCT |PROTEAN® i12™ IEF System Optimize experiments in fewer runs Run multiple experiments simultaneously Get more consistent results Learn more >> Overview Image PROTEAN® i12 IEF System Image PROTEAN i12 IEF Specifications For first-dimension IEF separations, the PROTEAN i12 IEF system uses IPG strips. The first dimension separates proteins based on isoelectric point (pI). Category Products Image PROTEAN® i12™ IEF System The PROTEAN i12 system has individual lane control, giving you the unique ability to run different samples, pH gradients, and protocols simultaneously. Image ReadyStrip™ IPG Strips IPG strips simplify first-dimension separations by immobilizing the pH gradient on an easy-to-handle support strip. ReadyStrip IPG strips are cast using high-purity IPG monomers. Image Tube Gel IEF Systems Several options for first-dimension tube gel separations for electrofocusing and analytical electrophoresis applications using ampholytes are offered, as are accessories. Image Model 111 Mini IEF Cell The Model 111 mini IEF cell performs analytical IEF, including isoenzyme separation, forensic applications, and clinical determinations.
