Protocol[edit]

  • Determine the concentration of Agarose to be used
                                                                  (1 Tray)
            DNA Size                            5 - 10 kb                           0.2 - 1 kb 
  Concentration of Agarose                        0.7 %                                 2 % 
      Amount of Agarose                            0.7 g                                2 g 
 Amount of 0.5X TBE Buffer                       100 mL                               100 mL 
    Amount of SYBR Safe                            8uL                                  8uL 

Note: Scale up or down accordingly

  • Weigh out the required amount of Agarose with a scale
  • Measure the required volume of TBE buffer using a graduated cylinder
Caution: Hot Agarose solution should be handled very carefully.  
  • Transfer the Agarose powder into a 250mL Erlenmeyer flask and add in the TBE buffer, mix by swirling the flask and microwave for 30s
  • Repeat mixing and heating step until all gel powder are dissolved and the solution appears to be clear
  • Let cool for a while and add in the required amount of SYBR Safe, swirl flask to mix the dye
  • Cast gel into tray with the required comb set in the tray
  • Let cool
