7/9 Did minipreps for multiple pMAX-GFP colonies, combined all the plasmids into one microcentrifuge and the yield was 249.4ng/ul.

Made a digestion, Cathy ran a gel

Cathy, and I worked on analyzing FACS results from Tuesday and Wednesday's transwells/transfections. Analyzed data on the Flowjo program; organized the data on excel, then put the results on a bar graph.

7/8 Transwell 8 variations of the RASSL hM4. The 8 were L1, L2, L3, M1, M2, H1, H2, and H3

Chemoattractant Dilutions CNO (0nM, 10nM, 100nM, 1uM)

7/7 Transfection (Contransfection) Add two constructs/vectors into our HL-60 cell line (RASSL + pMAXGFP) Use 5 days HL-60 differentiated with DMSO

Transfected hM2, hM3, hM4, Rs1.3, all including pMAXGFP into HL-60 cells Incubate in 37C for 4 hours. Used for transwell assay.

CNO Dilution is 10nM fMLP Dilution is 10nM

7/6 We used Amaxa transfection to get pMAX GFP DNA into 4 days HL-60 cells

Protocol provided from: http://cellpropulsionlab.pbworks.com (copied over from limwiki.ucsf.edu)

100ml monocyte media for HL-60 cells

78ml Gibco IMDM

20ml 20% FBS

1ml Glutamate

1ml Antibiotic/Antimycotics


2.75ml Nucleofector solution

2.25ml Cell Line Nucleofector Solution V

.50ml Supplement


Positive transfection showed cells with green fluorescence, there was about 40% fluorescence meaning 40% success rate. We have to note that using the right centrifuge makes a difference in transfection results. Using the incorrect centrifuge resulted in lower cell count and a 30% fluorescence while the correct centrifuge resulted in a much higher cell count as well as a fluorescence of 70%.

7/2 Cathy, Caitlin and I learned how to analyze our cells with the FACS machine. Sometimes the FACS machine is not accurate, so we add beads to increase accuracy. The machine takes about 40 seconds per sample, we had 56 samples.

Beads stock is 1,000,000beads/ml, we used 25ul which is 25,000 beads. If we have 100 cells and 20,000 beads shown on the FACS, then we can assume that only 80% (20,000 of 25,000) of the cells and beads are shown, So 100% of the cells would be 125 cells. I learned how to analyze these numbers on a computer program Flowjo, excel, as well as on a graph.

7/1 Practice a second protocol runthrough of Transwell assay

6/29 First protocol runthrough of Transwell assay

6/25 Ran gels and checked dictyostellium confluency
