Dye labeled Probe Annealing Test – with Cy3-1st Rolony
- Figure out upper limit by Formamide concentration
- Done @ 11/18
Procedure
- 20x obj, 2048 x 2048 resolution, 16bit,
- Scan Freq. 600Hz --> Image quality is not different from 400Hz.
- Sample : MatTek Dish, made at 07/09
- Each stripping, and annealing : 15min incubation @ RT
- Process Steps
- Step 0 : Strip
- Step 1 : Cy5 in 2x SSC
- Step 2 : Strip
- Step 3 : Cy5 in 70% Formamide + 2x SSC
- Step 4 : Strip
- Step 5 : Cy5 in 10% Formamide + 2x SSC
- Step 6 : Strip
- Step 7 : Cy5 in 30 % Formamide + 2x SSC
- Step 8 : Strip
- Step 9 : Cy5 in 50% Formamide + 2x SSC
- Step 10 : Strip
- Step 11 : Cy5 in 70% Formamide + 2x SSC
Result
- 0~30% Formamide concentration showed similar number of rolony, but the number decreased at 70%.
- Need to try 20%, 30%, 40%, twice at each time in order to confirm 30% is maximum condition!
1st Rolony Count
- Before Step 0 (At the beginning Cy3 probe were annealed) --> 5932
- Step 1 : Cy5 in 2x SSC --> 5469
- Step 3 : Cy5 in 70% Formamide + 2x SSC --> 543
- Step 5 : Cy5 in 10% Formamide + 2x SSC --> 5413
- Step 7 : Cy5 in 30 % Formamide + 2x SSC --> 5446
- Step 9 : Cy5 in 50% Formamide + 2x SSC --> 4793
- Step 11 : Cy5 in 70% Formamide + 2x SSC --> 421
Formamide (%) | 1st Rolony Count |
0 | 5469 |
10 | 5413 |
30 | 5446 |
50 | 4793 |
70 | 482 |

- Stage was moveed a little from Step9 by mistake, so the location was re-configured.
