10:30A — 11:15 P

  • Overnight confocal quick check data look great.
  • Day 3 in situs (using new chambers).
  • WaP book6, ch23
  • Labeling secondary antibodies.  all are donkey antibodies from Jackson Immuno.  reported are absorption values from the spec at the corresponding wavelength peaks.
    • rb 750.   750=.80, 405=.18,280=.447.  3.8:2.4, con 1.3 uM
    • gt 647.   647=. 463, 405=.198,280=.419 3.9:1.3 1.3 uM
    • shp 750.  750=.661,405=.175,280 =.429  3.8:2.0  1.3 uM
    • gt 488 488 = .138, 280=.339
      0.99 dye/antibody.
    • shp 647: 647=.450,405=.212,280=.460  4.4:1.3, 1.4 uM
    • m 647:  647=.573,405=.216,280=.50,  4.0:1.5, 1.5 uM
    • rb 488: 488 = .22 – .07 bkd. 280 = .448-.07 bkg.
      0.96 dye/AB.  1.7 uM
    • m 488: 488 = .125, 280 = .25
      1.2 dye/AB   1.3 uM
    • shp 488: 488 = .109, 280 = .354
      1.6 uM  0.68 dye/AB = trash
  • concentrations and ratios computed with Graham’s calculator
  • Moved ‘Protocols’ to GoogleDocs
  • 7:40p Confocal laser heating up.  Found control should play around with it.
  • No success engaging direct focus.  MP08 snaD from 2-17 uses LacZ-dnp (poor choice).  some embryos found anyway.
  • System may have drifted back in Z during attempt at engaging focus drive and figuring out color channels.  Dropped 488 for speed, doesn’t seem to image well in 4 channel setup.
  • in situs stained and in final PBT rock at 4C O/N.  Tomorrow check staining on Zeiss700 and post-fix good embryos — proceed for embedding.
  • Found rat anti-DNP, free up rabbit channel for in situ / protein stain.
  • Set up 2 new wt cages (11:00P).
