Kristian, Gosia, Natalia, Henrike
Procedure
PCR for AMO
Made four reactions using 1 uL respectively 10 uL of culture from the -20 or from the glycerol stock (-80) as template and adjusted volume of water accordingly.
Primers 10a, 10b.
PCR for SPL (synthetic promoter library)
template: pZa21 with RFP, primers: 52a, 52b1, temperature: 50C, time: 2:30
PCR for reference promoter
template: pZa21 with RFP, primers: 52a, 52b2, temperature: 50C, time: 2:30
PCR for araBAD K808000
template: K808000, primers: 12a, 12bn, temperature: 50C, time: 2:30
PCR to extract Nir2 from P. aeruginosa
PCR for araBAD and SPL with DMSO
Template and primers as previous.
PCR on Nir1 with MgCl2 gradient
Used previous isolation from a gel purification to make PCR for amplification of the strand. Used 5% DMSO as additive. The PCR was done with primer pair 41 and with x7 polymerase at 55C annealing and 5:00 min extension. Also we used 20 sec as denaturing time instead of the normal 10. The magnesium gradient was as follow:
- 0
- 1uL MgCl2 2mM per 50uL reaction
- 5uL MgCl2 2mM per 50uL reaction
- 20uL MgCl2 2mM per 50uL reaction
Gel purification
of the Nir1 fragment extraced from P. aeruginosa. Nanodrop: 8ng/uL
Plasmid miniprep
HAO in pZA21 from USER cloning was purified for restriction analysis. Nanodrop measurement: 180ng/uL
