Product Description

  • The JSB-302 is designed for nucleic acid screening electrophoresis.
  • Use for mini gel format quick screens with twice the number of samples.
  • It utilizes a wider format than the traditional mini-submarine electrophoresis system JSB-30.
  • This system can process a large number of samples and is ideal for PCR, fragment analysis, or recombinant screening.
  • It is a 15cm x 10cm mini gel in a horizontal format that can run up to 36 samples in under 30 minutes.
  • Constructed of 1/2" thick cast acrylic, the JSB-302 is designed to provide years of continuous service.
  • The maximum suggested applied voltage for the electrophoresis of DNA in agarose gels using the JSB-302 is 150 volts. In a 1% TBE gel, this translates into a run time of approximately 1 hour. Lower voltages may be used, of course, and as a general rule, a 75 volt run will take twice as long as a 150 volt run. Higher voltages may be used to decrease run time; however, if the unit is being operated at higher voltages than 150 volts the heat generated during electrophoresis may decrease sample resolution. Such artifacts may be avoided by running the unit in a cold room or adding 1X electrophoresis buffer "ice cubes" to keep the unit properly cooled.
  • The suggested run parameters for the electrophoresis of RNA in agarose gels containing formaldehyde are 60-80 volts.
  • The JSB-302 offers the user three different length gel trays. The 10cm long tray comes with the unit and the 7.5cm and 5cm long trays can be purchased separately, along with their corresponding casting fixture tray.
  • Comes complete with Lid, Buffer Tank, UVT Casting Tray (15cm x 10cm), Casting Fixture (10cm), one 1.5mm x 27 Tooth Comb, Comb Holder, Bubble Level, Adjustable feet, and Power Cords.
