Notes

  • HeLa cells had less sample put too gel, both HEK293 and HeLa are very slimy
  • Forgot to lyse the ordered HEK293 cells
  • Blot was blocked ON in 1% BSA in TBS-T
  • Gel was Coomassie stained ON

Results

  • Overnight autoradiograph of RII overlay did not change anything of the image of yesterday
  • Ponceau of cAMP pull down SDS-PAGE

Discussion

  • Ponceau shows bands at higher altitude, maybe look for AKAP-Lbc next to AKAP250?
  • Anoying that both markers are not running equal on every height, but HiMark at least has nice sharp band @ 160 kDa on NuPage gels. Although transfer was less perfect
  • Coomassie staining shows not a 100% efficiency of transfer, and it shows bands in the control lanes that were not visible on Ponceau staining. Hopefully something did transfer
