System Description (for which this component is intended)

Bio-Rad CHEF MAPPER XA PULSED FIELD ELECTRPHORESIS SYSTEM

The CHEF Mapper system is based on two leading technologies, CHEF (clamped homogeneous electric fields)31 and PACE (programmed autonomously controlled electrodes).32 The system provides highly uniform, or homogeneous, electric fields within the gel, using an array of 24 electrodes, some of which are clamped, or held to intermediate potentials to eliminate lane distortion. Thus, lanes are straight. The system maintains uniform fields using patented Dynamic Regulation (US patent number 4,878,008). The electrodes sense changes in buffer conductivity due to buffer breakdown, buffer type, gel thickness, pH fluctuations, and temperature, and potentials are readjusted immediately to maintain uniform fields, thus insuring high resolution. In PACE, each electrode s voltage is controlled independently by firmware. Whereas other CHEF systems are limited to two vectors and a 120° pulse angle, the CHEF Mapper system allows up to 15 vectors per block with a total of 8 blocks, each vector with its own voltage, angle, and duration. Thus, the CHEF Mapper system may simulate virtually any pulsed field technique using homogeneous fields, including FIGE, CHEF, and RFGE. Advanced programmers may simulate OFAGE and other non-homogeneous field methods using a computer.

The CHEF Mapper system offers innovations beyond original PACE. For example, nonlinear switch time ramping allows linear separations for many sizes of DNA. Secondary pulses, or interrupts, unhinge DNAs from obstructions and permit faster separations. The CHEF Mapper system contains 5 years of protocols embedded on a microchip, eliminating trial and error in setting parameters. Given the size range you expect to separate, the embedded auto algorithm interrelates the sizes with 10 other variables, and provides the preferred operating conditions. Common gel and buffer conditions, and run temperature of 14 °C, are assumed. An Interactive Program Disc provides an extended version of the algorithm. This PC program allows you to vary gel, buffer, and temperature parameters and print out optimal conditions.

We offer a Bio-Rad Chef Mapper in good physical condition. The unit powers on fine. Compressor Kicks on and cools to temp.
