Laser powers

  • 405: 1.5 mW
  • 488: 115 mW at 45% power
  • 561: 135 mW at 200 mW GUI/laserhead
  • 642: 135 mW at 200 mW GUI/laserhead
  • 750: 250mW at 1800 mA. –> too high?
  • 750: 120 mW at 1400 mA –> too low?
  • 750 190 mW at 1600 mA try this

Observations on switching

  • 647 still switching rapidly with 4.8% 405 at 50K frames.
  • 488 swtiching looks much better after ~40K frames.  Still switching strong.

cryo-sections:

  • cent-647 dramatically dimmer (due to overlong overhot hot washes? / lost probe?).  488 H3K9me2 very bright.
  • sections very not flat
