Mini spin prep on LC and HC colonies
Place DNA in 100μL H2O in freezer
July 29, 2008
All primers brought to standard concentration, 30mM
33.3μL H2O added per n mole of primer

Master mix already contains MgCl2; should have added extra to some tubes.
PCR program
- 94 degrees 5 min

- 72 degrees 1 min
- GOTO 2. 29 cycles
- HOLD at 4 degrees
1.5% agarose gel made, 0.75g agarose in 50ml 0.5X TBE w/10ul EtBr.
20ul of PCR produts loaded on gel w/4ul 6X loading buffer, run at 200V for about half an hour.
All lanes had lots of DNA at ~375bp, PCR worked.
July 31, 2008
PCR to asemble fragments from yesterday.

- 50 degrees 1 min
- 72 degrees 1 min
- GOTO 2. 29 cycles
- 72 degrees 5 min
- HOLD at 4 degrees
Products run on a 1.5% agarose gel, no products of 700-800bp.

PCR troubleshooting of yesterday's reaction: use gradient for annealing temp (40-65 degrees), use more template, leave out end primers
Four series of reactions using a gradient annealing temp were run in addition to a fifth series omitting the end primers.
| reaction series | A | B | C | D | E |
| template (5+7) from 7-30 PCR | 0.5ul | 1ul | 1.5ul | 2ul | 1ul |
| primers | 1ul of forward and reverse primers (omitted in E series) | ||||
| master mix | 20ul | ||||
| H20 | to 50ul total volume | ||||
annealing temps: 40, 43.8, 50, 54, 60, and 64 degrees
PCR program
- 94 degrees 5 min
- 94 degrees 1 min
- annealing step 1 min
- 72 degrees 1 min
- GOTO 2. 29 cycles
- HOLD at 4 degrees
PCR products run on 1.5% agarose gel at 200V for ~20 minutes, then 240V for ~20 minutes.
Products in the 700-800bp range in all lanes. Perhaps it worked because of using a differnt product from the 7-30 PCR.
August 6, 2008
1.5% agarose gel of 8-1 PCR products run to cut out bands. Products A1, B1, C1, and E1 used.
Bands around 800bp cut out for all lanes and invitrogen gel extraction kit used to collect DNA in 50ul H2O.

Flk-1 clones from [http://www.atcc.org/ATCCAdvancedCatalogSearch/ProductDetails/tabid/452/Default.aspx?ATCCNum=MGC-18600&Template=mgcMouseClones ATCC] streaked onto LB+amp and incubated at 37 degrees.
September 6, 2008
Colonies picked from flk-1 plate and inoculated into 5ml LB+amp, grown at 37 degrees.
Freeze-dried e. coli with YCp50-poly from [http://www.atcc.org/ATCCAdvancedCatalogSearch/ProductDetails/tabid/452/Default.aspx?ATCCNum=87555&Template=vectors ATCC] resuspended in 5ml LB, grown at 37 degrees.
