The new Vertical Maxi Z system from Alpha Laboratories is the latest product innovation for large-format vertical gel electrophoresis. Designed to perform a variety of separations, including first- and second-dimension SDS-PAGE, native, preparative, gradient and high-resolution nucleic acid electrophoresis, plus capillary tube gel IEF and electro-blotting, Alpha Laboratories says that the Maxi Z is one of the most versatile maxi vertical systems available.
By introducing innovative, new vertical screw-clamp technology within the PAGE insert, only four screws are now necessary to secure as many 20x20cm gels. This gives the Maxi Z the selective advantage of a much faster set-up speed compared to other products whose traditional clamping configurations require as many as 24 screws to secure just two glass plates. In addition, the Maxi Z’s vertical screw-clamp configuration distributes pressure evenly along the height of the gel rather than in the centre to eliminate plate bowing and gel compression, but still maintains a leak-proof seal during casting; while the ergonomic Z-like design of the PAGE insert aids both handling and set up.
Whatever the user’s requirements are, the Maxi Z can be made to meet them. Regardless of whether it is running two or four gels, electro-blotting, and IEF using capillary tube gels or IPG strips, all of these techniques may be performed using the same all-purpose unit while retaining the benefits of large format electrophoresis, such as extended separation distances, greater sample throughput and superior resolution.
