Computer issues

  • Attempted to swap memory into Cajal.
  • Cajal won’t boot up with any of the memory
  • restored Tuck to 6x 8GB DIMMS.
  • Cajal has 12x 4GB DIMMS
  • wrote to IT to help get system back up.

PH project: requests from Ajaz

  • pick some poly-lysine tonight around 6:45pm?
  • Below are the things which need to be adjusted for main model figure. We need to reorganize the model figure (no. 6). In this figure we need
    1. two schematics for models
    2. plot showing fraction clustered as a function of PH-ML conc.
    3. Representative images
    4. Plot showing diameter varying as a function of PH-ML conc. OR distributions of cluster diameter at different conc. of PH-ML as you plotted for low, mid and high PH-ML concs. (Here I wonder if we show plot for cluster size vs PH-ML conc. we might need to run simulations to show how diameter changes as we increase the PH-ML conc. Something similar to what we have for fraction clustered vs PH-ML conc. plot)
    5. Please see Bob’s comments regarding this figure also. (in the manuscript revised by Bob) According to him schematics are not easy to follow and simulated lines should be smoother (which I think means running the simulations many more times)
  • Actually let’s put this on hold. Currently redrafting paper into shorter 4-fig version and I don’t think there will be time or space for the modeling.
  • still should run PSC clustering data.

Probe Making

  • run oligo-clean and concentrate of probes
  • quantify probe concentrations

E5-E12F1-F8_probes

Troubleshooting labeling

  • Re-measured temperature of hot-plate.
    • setpoint 88C, read with block inverted, thermometer on top, now 78C. Used this for hybes.
    • setpoint 85C, read with block inverted, thermometer on top, temp 71C.
    • setpoint 88C, read with block right-way-up, embedded thermometer, 81C
    • setpoint 85C, read with block right-way-up, embedded thermometer, 78C

New stains

  • C07 treat with 2x SSCT 50% form along with other cells when they come out of RNase. Restain with E04 probe. Denature at usual 85C (glass temp ~78C).
  • new cells RNase treated, extended prehybe at 47C. stain with C01. Denature at usual 85C
  • new cells RNase treated, extended prehybe at 47C. stain with C01. Denature at 100C (glass temp will be 95C at best)
  • Aim / hope: RNase treatment decreases background from expressed locus, extended 47C prehybe increases suspetability to melting during denaturing step.
  • hope 2, change in hot-plate as source of problem now fixed?
  • old cells, RNase treated, stain with new E06 probe (1.5 uL of 2,000+ng/uL probe + .5 uL primary)
  • old cells, RNase treated, stain with new E07 probe (3 uL of ~800+ng/uL probe + .5 uL primary)

OligoSecondaries

  • working on methods section for paper
  • sent current working draft back to Brian.

Review

  • finished checking equations, found small error in my calculations. Still don’t match authors calculations.
  • finished writing up review comments and submitted review.
