pfu PCR of B0015 and PCR purification
date: 17/8
Protocols: CP1.1 and GFX easy protocol
Notes:
2 uL PCR product of B0015 (no. 43 white) was used as template for each PCR reaction.3 PCR reactions were prepared.
Premix for 4 PCR reactions:
| 25uL | pfu bf. + MgSO4 |
| 7,5uL | dNTP's |
| 7,5uL | VF2 |
| 7,5uL | VR |
| 190uL | H20 |
| 2uL | pfu Polymerase enzyme |
48uL premix is distrubuted into each PCR tube. PCR tubes are marked B0015.A-C
PCR program:
| Start | 95C | 3min |
| Denaturating | 95C | 2min |
| Annealing | 55C | 30s |
| Elongation | 72C | 45s |
| Go to | 2 | 29x |
| End | 72C | 2min |
| Hold | 4C |
5uL of PCR sample is loaded onto a 2% agarose gel. Generuler 100bp DNA ladder (blue) is used as marker.
Results:
Analysis:
PCR product is OK and B0015 DNA is purified from the PCR product according to protocol. DNA is eluted in 20uL H2O. Purified samples are stored in the jumblebox (hotchpotch), marked as B0015-1 and B0015-2.
Group: Retinal
Characterization of Beta-carotene
Start date: 10/8
Methods: ON, sonication, UV-vis spectroscopy
Protocols: CC.1.1[1]
Colony PCR on transformants using ninaB fwd and rw primers
Date: 10/8
Done by: Christian & Tommy
Methods: ON
protocos:
Notes:
ON was made from 4 colonies:
Top 10 - on insert -> OD = 0,008 (100 x diluted)
Top 10 - with K274210 biobrick insert -> OD = 0,011 (100 x diluted)
MG1655 - on insert -> OD = 0,020 (100 x diluted)
Mg1655 - with K274210 biobrick insert -> OD = 0,017 (100 x diluted)
ON was made in 110 ml LB media. colonies with K274210 biobrick insert was grown in media containing ampicillin.
alle the ON cultures was grown for 20 hours at 37 °C.
After 16 hours, ml of the ON colonies was transferred in to 110 LB media and grown for 4 hours to the exponential phase:
Top 10 - on insert -> OD = 0,049 (100 x diluted)
Top 10 - with K274210 biobrick insert -> OD = 0,044 (100 x diluted)
MG1655 - on insert -> OD = 0,007 (100 x diluted)
Mg1655 - with K274210 biobrick insert -> OD = 0,009 (100 x diluted)
Colonies with K274210 biobrick insert was grown in media containing ampicillin.
Harvesting, sonication and UV-vis spektroscopy
Date: 11/8
Done by: Christian & Tommy
Methods: Cell harvesting, sonication and UV-vis messurements
protocos: none
Notes:
100 mL Cell cultures was centrifuged for 5 min at 14000 RPM. the supernantant was discarded and cells were resuspended in 5 mL acetone (99,9%), except the top 10 with the K274210 biobrick insert wicht was resuspended in 10 mL acetone (suorce of error.). The resuspended cells were sonicated for 5 min. the samples were spun down and the supernantant were transferrede to new tubes, cell bebri was discarded.
