Bleomycin resistance gene
Resistance gene for algae expression. Bleomycin gives a resistance against zeocin, because ble binds to zeocin blocking its funtion.

After ligating the sequence in the pJP22, we wanted to find the best way to transform C. reinhardtii, we tested Sapphire Blue, TAP medium and water as buffers during the electroporation. Then, cells were plated in Agar-TAP medium Petri dishes with different concentrations of Zeocin (an antibiotic from Bleomycin family) because the plasmid used had a sequence for Bleomycin resistance.

As expected, the number of colony-forming units is much higher in the media with less Zeomicin.
At the same time, the transformation of cells were not so good using Sapphire Buffer in comparison with Water and TAP medium.
