Product Description

IBI Quick Screen Horizontal Electrophoresis System is constructed of 3/8" thick durable cast acrylic that resists cracking and warping for years of use.

  • Designed for rapid linear separations of nucleic acids. It requires minimal setup and provides excellent band resolution with consistent lane-to-lane mobility for accurate results. It is versatile for use with applications requiring quick screens, such as fragment analysis and recombinant screening, all in 30 minutes or less.
  • The maximum suggested applied voltage for the electrophoresis of DNA in agarose gels, using the QS-710, is 100 volts. In a 1% TBE gel, this translates into a run time of approximately one hour. Lower voltages may be used with the general rule that a 50 V run will take twice as long as a 100 V run. Higher voltages may be used to decrease the run time; however, the heat generated during high voltage electrophoresis may decrease sample resolution. Such artifacts may be avoided by running the unit in a cold room or by adding 1 X electrophoresis buffer "ice cubes" to keep the unit properly cooled.
  • The suggested run parameters for the electrophoresis of RNA in agarose gels containing formaldehyde is 60-80 volts. Since the QS-710 has no capacity for buffer recirculation, the buffer from each reservoir should be collected after 1.5 hours of electrophoresis.
  • Casting Tray bottom is constructed of UV Transmittance cast acrylic to allow viewing of gel with a UV light source.
  • The IB51000 has a patented vented lid dissipates heat for cool and fast separations. Patent# 5,779,869.
