The Biotechnology students had a fun lab yesterday. Dye electrophoresis is done with a food color for the dye which is mixed with glycerol. The students worked on their pipetting skills by placing 20 microliters of the dye into the wells of agarose gel. The elctrophoresis unit is then plugged in to a power source and observed after a few minutes. All colors migrated to the positive post except for the blue color which went to the negative. We did this over a two day period so plenty of hands-on experience was accomplished.
