Lab 208

Main purpose

PCR for AMO with USER endings.
Extraction PCR of Nir1

Who was in the lab

Kristian, Julia, Henrike

Procedure

PCR for AMO with USER endings

primers: 17a, 17b

template: gel purified AMO extraction fragment

Program: Standard with 54C annealing temperature and 3:00 extension time

Reaction Mix

component(per reaction)	without additives	using 5% DMSO	using 1M Betaine
dNTPs	1uL	1uL	1uL
HF buffer	10uL	10uL	10uL
X7 polymerase	0.5uL	0.5uL	0.5uL
MilliQ water	31.5uL	29uL	21.5uL

PCR for extraction of Nir1

primers: 41a, 41b

template: colony from plate. One colony was dissolved in 100 uL of MilliQ and 1 uL of this solution was taken as template

program: Touchdown PCR analog to program used on 01-08-2013 to amplify Nir.

Conclusion

Today's PCRs on AMO and Nir were successful when DMSO was added.

Lab 115

Main purpose

Run Experiment 2. E.coli control measurement.

Who was in the lab

Ariadni, Natalia

Procedure

Adjusting the temperature at 37<up>o</sup> and calibrating the probes as described in Appendix 5.

Following the protocol Experiment 2

Changing the steps :

19. Add 0.5 ml of nitrite solution and continue by adding 0.5 ml after 10 minutes.

We added 0.5 ml nitrite again and then we took 2 ml of sample, we added then 0.5 ml and afterwards when there was any change in the curve we spiked with 0.4 ml of nitrite. We took 2 ml for sample in the end and we added 0.5 ml of N₂O and 1 ml of NO to see if the probes are working properly.

Results

Colorimetric results

Measurements of standard solutions

Ammonium - 43.7 mg/L ( expected 39 mg/L)

Nitrite - < 2 mg/L (X10 diluted) -0.4 mg/L (with no dilution) (expected 0.5 mg/L)

Nitrate - 18.7 mg/L (X10 diluted) (expected 12 mg/L)

Measurement of samples

Ammonium

Measuring range 2-75 mg/L NH₄-N

start point- no signal

middle point- signal <2 mg/L

end point- signal 0.7 mg/L

Nitrate

Measuring range 1-25 mg/L NO₃-N

start point- no signal

middle point- signal <1 mg/L

end point- signal <1 mg/L

Nitrite

Measuring range 0.02-1 mg/L NO₂-N

start point- no signal

middle point- signal 0.43 mg/L

end point- signal 0.79 mg/L

Conclusion

Problems with the NO probe and there were not proper results.
