Glycerol stocks of MG43, MC42, MC43. Static TECAN test (absorbance, green fluorescence and red fluorescence) on 200 ul of these cultures.
Cultures were diluted in 4 ml final of LB in order to obtain the same lowest OD with the following formula: culture to remove and substitute with LB=FinalVolume-(lowestOD/misuredOD)*FinalVolume.
Centrifuge at 4000 rpm, 25°C for 5 min to pellet the culture, discard the surnatant and resuspend the pellet with 1 mL of M9. Static TECAN test (absorbance, green fluorescence and red fluorescence) on 200 ul of these cultures.
Liquid PCR was performed on MG43 (3 colonies), MC42 (3 colonies), MC43 (3 colonies), MC1061 (negative control) with the following parameters: T_annealing=52°C, cycles composed by 10 min at 94°C, 30 sec at 94°C, 30 sec at 52°C and 4 min at 72°C . This is the result:
 PCR results for MG43 A-B-C, MC42 A-B-C, MC43 A-B-C, MC1061. The last lane is reaction blank.
MiniPreps of I44-1:5 and I51-1:5 were performed with these results:
| Culture | Quantifications (ng/ul)
|
| I44-1 | 11,1
|
| I44-2 | 9,9
|
| I44-3 | 12,3
|
| I44-4 | 11,4
|
| I44-5 | 11,4
|
| I51-1 | 13,6
|
| I51-2 | 19,4
|
| I51-3 | 16,5
|
| I51-4 | 13,3
|
| I51-5 | 21,8
|
Probably was used the ethanol buffer without adding before the ethanol, during the wash step and so the quantifications were so low.
Digestion of I44_1:5 and I51_1:5 performed as follow:
| Culture | Kind | Final reaction volume (ul) | DNA (ul) | H20 (ul) | Enzyme 1 (ul) | Enzyme 2 (ul) | Buffer H (ul)
|
| I44-1 | Screening | 25 | 21,5 | 0 | 0,5 EcoRI | 0,5 HindIII | 2,5
|
| I44-2 | Screening | 25 | 21,5 | 0 | 0,5 EcoRI | 0,5 HindIII | 2,5
|
| I44-3 | Screening | 25 | 21,5 | 0 | 0,5 EcoRI | 0,5 HindIII | 2,5
|
| I44-4 | Screening | 25 | 21,5 | 0 | 0,5 EcoRI | 0,5 HindIII | 2,5
|
| I44-5 | Screening | 25 | 21,5 | 0 | 0,5 EcoRI | 0,5 HindIII | 2,5
|
| I51-1 | Screening | 25 | 21,5 | 0 | 0,5 EcoRI | 0,5 HindIII | 2,5
|
| I51-2 | Screening | 25 | 21,5 | 0 | 0,5 EcoRI | 0,5 HindIII | 2,5
|
| I51-3 | Screening | 25 | 21,5 | 0 | 0,5 EcoRI | 0,5 HindIII | 2,5
|
| I51-4 | Screening | 25 | 21,5 | 0 | 0,5 EcoRI | 0,5 HindIII | 2,5
|
| I51-5 | Screening | 25 | 21,5 | 0 | 0,5 EcoRI | 0,5 HindIII | 2,5
|
Gel screening shows that all the constructs were ok, so we decided to choose I44-2 and I51-3.
