Protocol

1-Determine the concentration of Agarose to be used

            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

  • 2-Weigh out the required amount of Agarose with a scale and measure the required volume of

TBE buffer using a graduated cylinder

  • Caution: Hot Agarose solution should be handled very carefully.
  • 3-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.
