The Bio-Rad CHEF System Comb Holder (Model: 1703699) is a necessary accessory for using combs with the CHEF (Contour-clamped Homogeneous Electric Field) electrophoresis system. Thi s holder securely positions the combs in the gel casting tray, ensuring proper well formation for loading DNA samples. The CHEF system is a pulsed-field gel electrophoresis (PFGE) technique used to separate large DNA fragments. Combs are used to create wells in the agarose gel where DNA samples are loaded. The comb holder ensures that the combs are properly aligned and held in place during gel casting, preventing the wells from being distorted or damaged. This comb holder is compatible with various CHEF systems, including the CHEF-DR® II and CHEF Mapper® XA systems. It is a simple but essential tool for researchers using PFGE for applications such as genotyping, DNA fingerprinting, and analysis of large DNA fragments. Show more
