9:45 am – 11:30 pm

To do

  • submit review
  • book flights for EMBO (travel form / shuttle requests due on Friday)

Chromatin project

centromeric heterochromatin

  • downloaded dm3 heterchormatic assemblies from UCSC here: http://hgdownload-test.cse.ucsc.edu/goldenPath/dm3/chromosomes/
  • mapping previously imaged GREEN regions back to the chromosomes
    CentromericChromatinImaged_150812
  • download modENCODE chip data for heterchromatic regions
  • downloading data from modENCODE: http://data.modencode.org/?Organism=D.%20melanogaster
  • checking modENCODE data for agreement. Here is BXC for K79me3 (red), K27me3 (blue), K9me2 (green)
    modENCODE_Kc_ChIPdata
  • compare to van Steensel data we’ve been using:
    vanSteensel_Kc_ChIPdata_b
  • looks pretty good, let’s go on with this.
  • finished designing and assembling library. Will order tomorrow.

dual color labeling

  • 750-P3-BXC + 647-P1-L2F6 no spots 🙁
    • abbreviated wash. Try washing longer.
    • try G5 G6 instead

STORM

  • 750 laser desktop configuration file not running properly.

live imaging

  • construct 1: mmaple3-MCP in H293 cells
    • looks good! we see some telomeres
  • construct 2: mmaple3-PCP in H293 cells
    • also looks good, a bit more backgroundy
  • construct 3: PCP-tagRFP in H293
    • looks good. maybe best yet (though not STORMable)
    • took some movies (called tagRFP) can estimate positional stability.
  • construct 4: U2OS cells, gRNA co-transfect. TagRFP-PCP
    • a lot of uber bright nuclei with nuceleolus stain
    • not so good
