| In order to detect the pathogens fast, specifically and inexpensively we are building sensor cells to detect these pathogens. These sensor cells can identify pathogens in very low concentration by responsing to specific extracellular molecules either secreted by or displayed on the pathogens. These molecules trigger a fast fluorescence response by our immobilized sensor cells  which will be measured by our device.

* He also added 170&nbsp;µL of the glucose stock (500&nbsp;g/L) to the glucose-free HM+C-plates
+
-
* 1&nbsp;L of sterile HM+glucose was prepared
+
-
* K731520 iLOV was plated on HM+C+Glucose and HM+C+Glucose drops, 3x 5&nbsp;mL HM+C+Glucose precultures were inoculated (17:00)

-
 
+
-
== 24th ==
+
-
* K731520 iLOV did not grow, neither on the plates, nor on in the liquid media. The most probable cause is that the ''E.&nbsp;coli'' is missing some vitamins
+
-
* Based on the [http://openwetware.org/wiki/M9_medium/supplemented M9 recipes by the Knight and Endy labs on OpenWetWare], we made a 20&nbsp;mL supplement stock solution that can be added to 1x HM media

In the evening, we plated some strains on the different media to investigate why the K731520 iLOV did not grow on the HM+suppl. plate. (Note: In the morning, [[User:mosthege|Michael]] re-inoculated the HM+C+suppl. shake flask with cells from the LB-plate and by afternoon the culture ''did'' grow to a high cell density.)

+
-
* [[User:Nbailly|Nina]] tested the growth of ''Pseudomonas fluorescens'' in different liquid media for high OD and strong fluorescence. She tested Standard I medium, Cetrimide medium and Pseudomonas-F medium, and Pseudomonas-F medium supplemented with 300&nbsp;µL Fe3+ in 500&nbsp;mL flasks with a filling volume of 30&nbsp;mL. The flasks were inoculated with ''P. fluorescens'' cells on Standard I agar, and incubated at 30&nbsp;°C at 250&nbsp;rpm.

* plasmid prep of I20260, K516032 and B0034
+
-
* restriction of plasmids I20260, K516032, B0034 with EcoRI and PstI
+
-
* A gel with restricted the I20260, K516032 and B0034 was run.
+
-
* purification of vector backbones pSB1A2, pSB3K3 and pSB1C3
+
-
* restriciton of synthesized TEV protease with EcoRI and PstI
+
-
* [[User:Nbailly|Nina]] qualitatively tested the ''Pseudomonas fluorescens'' that had grown over night for OD and fluorescence. She determined that Pseudomonas-F medium is the most adequate for the cultivation of the strain we use, since both OD and fluorescence were best in the flask containing the respective medium.

-
GFP_Reach 2 clone #3 and #5 were fine, including the Leu to Ile mutation.

-
GFP_Reach 1 clone #4 and #5 were fine and did not contain the Leu to Ile mutation. Clone #6 was fine but contained the Leu to Ile mutation from the Reach 1 quick change mutations.
+
-
 
+
-
For future experiments, we will use the GFP_Reach 1 clone #4 and the GFP_Reach 2 clone #4.
+
-
 
+
-
Transformation of GFP_Reach 1 clone #3 and GFP_Reach 2 clones #3 and #5 were performed together with the TEV protease to create two plasmid construct.

* [[User:Nbailly|Nina]] tested ''Pseudomonas fluoresence'' if they are suitable for a growth experiment that is planned for our collaboration with the NEAnderLab next week. Therefore, she filled 2 500&nbsp;mL flasks with 30&nbsp;mL LB Pseudomonas-F medium, and inoculated each one with 1&nbsp;mL culture medium of the overnight preculture. Flasks were inoculated at 30&nbsp;°C at 250&nbsp;rpm. However, after 5 hours no exponential growth could be shown (s. plot below). Thus, it was decided to use a ''E. coli'' K12 derivate strain in TB medium instead, and 30&nbsp;mL of TB medium in a 500&nbsp;mL flask were inoculated with ''E. coli'' DH5alpha cells and incubated at 37&nbsp;°C at 300 rpm over night. According to the [https://www.dsmz.de/catalogues/catalogue-microorganisms/groups-of-organisms-and-their-applications/strains-for-schools-and-universities.html DSMZ] ''E . coli'' K12 strain derivates, such as DH5alpha, are adequate for the kind of school experiment we are planning with the NEAnderLab.

Inoculation was done via precultures in 500 ml shake flasks (50 ml filling volume). Media was always LB. Cultivation was done at 37°C and 300 rpm. The starting OD was aimed to be 0.1. Inoculation occured directly from the precultures. Samples were taken every hour and checked for OD and fluorescence using a spectrophotometer and plate reader, respectively.
+
-
 
+
-
* [[User:VeraA|Vera]] did a plasmid preparation from the cultures of the day before (K1319013, K1319013 + K1319008, K1319013 + K1319008 + iPTG, K1319014, K1319014 + K1319008, K1319014 + K1319008 + iPTG, B0015 and I20260). The plasmid were then be cut with EcoRI and PstI, and the results were be put on an agarose gel in order to perform a restriction test.  Also plasmids of K1319013 and K1319014 will be cut with EcoRi and SpeI. K1319008 will be cut with XbaI and PstI. These will then be ligated together and then ligated into a pSB1A3 vector via the 3A assembly (vector cut with EcoRI and PstI). These constructs will be transformed into BL21 (and NEB as a backup). The created construts will be known as K1319018 (K1319013.K1319008) and K1319019 (K1319014.K1319008).

-
* [[User:fgohr|Florian]] made precultures of the master plates from the day before (K1319008, K1319013, K1319015 and pSBX1A3 with Gal3).
+
-
 
+
-
* [[User:AZimmermann|Arne]] also inoculated 4 cultures for the further testing of the OD/F device (the F part). The cultures are 2 shake flasks of I20260 and 2 shake flasks of B0015.
+
-
 
+
-
* Furthermore, [[User:Nbailly|Nina]] did a growth experiment with DH5alpha for the NEAnderLab school experiment. 3 500mL shake flasks were filled with 50mL TB medium, and inoculated to an OD of 1.5 with the overnight preculture. Samples were taken every 30 minutes and tested for OD using our own device as well as the spectrophotometer. The resulting growth curve is shown below. [[User:Nbailly|Nina]] concluded that the growth was fast enough for these growth conditions to be used for the school experiment on the 24th.

Then they will be induced with iPTG/HSL and fotos will be made every 30 minutes to check for fluorescence (GFP).
+
-
 
+
-
* [[User:fgohr|Florian]] tested our OD/F device with a dilution test. Samples were checked with the spectrophotometer (OD), our OD/F device (fluorescence) and platereader (fluorescence).
+
-
 
+
-
* [[User:Aschechtel|Anna]] and [[User:VeraA|Vera]] made SDS gels.
+
-
 
+
-
* [[User:User:StefanReinhold|Stefan]] inoculated a culture of K1319008, B0015 as well as I20260 to check whether the results from our construct are from a wrongly done Gibson assembly with a still functioning superfolded GFP (the TEV protease was inserted in a backbone that formely contained superfolded GFP.)

* [[User:Mosthege|Michael]] did a check PCR on several cryo cultures. All samples with G00100_Alternative+K1319004_check_R combinations resulted in a strong band at ~2300&nbsp;bp that we cannot explain. All G00100_Alternative+K1319004_check_R combinations resulted in a strong band at 900&nbsp;bp that we cannot explain either. We concluded that the annealing temperatures were wrong and favored unspecific products. Therefore, we decided to do a gradient PCR to find out the optimal annealing temperatures for our new primers.
