Summary

Today the U2OS culture in 6-well plates looks ready for transfection (~80% confluency) and the KAH126/U2OS culture in 6-well plates looks ready for induction by doxycycline (~80% confluency). I'll be taking care of that, as well as running a plasmid mini-prep on some E. coli cells I grew up and harvested earlier in the week.



Goals

  • Transfect U2OS cells
  • Induce KAH126/U2OS cells
  • purify KAH126/MV2 plasmid from E. coli



Protocol

  • mammalian tranfection w/lipofectamine
  • Doxycycline induction of KAH126/U2OS cells - just add 1uL of doxycycline per mL of medium in each sample to be treated.
  • Plasmid prep - follow instructions in the Sigma plasmid mini-prep and in the cloning bootcamp

Average concentration of plasmid from colony 1: 96.163 ng/μL

Average concentration of plasmid from colony 2: 59.2485 ng/μL

NOTE: All of the plasmid collected from colony 1 was consumed in the transfection of the U2OS cells today. The wells transfected with the new plasmid were #'s 3 and 4.
