6/6/16: ARB KB SC TM Made LB Broth 6/7/16: ARB KB SC TM Screwed up yesterday, made more LB Broth Made 50 mL overnight culture of hef1a-tagBFP 6/8/16: ARB KB SC TM Midiprepped hef1a-tagBFP; midiprep failed (very low concentration) 6/9/16 ARB KB SC TM Midiprep for hef1a-tagBFP; failed again

  • One lysate solution of the two spilled a bit during vacuuming, will probably use the other for transfection if it results in higher concentration
