Stage adapter detachment and reinstall test[edit]

  • Use 10/22 sample, which was used for the experiment yesterday (10/28)


Procedure[edit]

  • Image – 3 channel along Z stacking
  • Save location (Mark and find function)
  • Lower objective, detach stage adapter, move stage to left side far from original position
  • Reinstall adapter
  • Move stage back to saved position, and image


Result[edit]

  • 7 pixel, 281.25nm x 7 = 1.96875um off to upper direction.
  • There was no offset at other direction.
  • Composite image, Left:Before, Right:After (Blue : 1st rolony, Red : ACTB, Green : RAB7A)

Adding ACTB probe only[edit]

  • Image the sample with 3 dye probes
  • Strip, and image again
  • Add ATTO488, ACTB probe only, imaging


Result[edit]

  • ACTB were found more than before… WHY?
    • This is maybe because those dye compete each other while annealing. Or one dye lost it's intensity because some percentage(it'll be very little though) of the dye's emission energy is used for excite another dye, so Cy5 signal is always brighter than other two dye.
