| 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.

* [[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: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.

The results of these three PCRs are:

-
# The KAPA2G Fast ReadyMix worked well

-
# The K1319008 template was contained I746916 instead of the intended K1319004 ORF

It was concluded that a similar check PCR with 65&nbsp;°C annealing temperature will be done on all plasmids and cryos of K1319008.

The resuspended cultures were mixed with 49 mL LB+agarose and poured onto three sensor-chip-templates (one template per culture).

**At 13:30 [[User:PatrickO|Patrick]] prepared 150 mL LB+agarose medium (1.5% (w/v) agarose). The LB+agarose solution was autoclaved and subsequently tempered to 45 °C. Precultures (50 mL each) of B0015 and K1319017 and K131026 were spinned down at 3000 rpm (?check?) for 10 min at 21 °C and resuspended in 1 mL pretempered (21 °C) LB-medium. The resuspended cultures were mixed with 49 mL LB+agarose and poured onto three sensor-chip-templates (one template per culture). Sensor chips were cut out from the template and incubated at 37 °C for 1 h.

**B0015,K1319017and K131026 were induced with 0.2 µL homoserinlacton stock solution (50 µM). The induced sensor-chips were read out evry 30 minutes for 240 minutes in total. Readout was conducted at 450 nm and 480 nm wavelength. An additional readout was conducted after 12 hours.

+
-
*At 17:00 [[User:PatrickO|Patrick]] prepared 4 liquid cultures from the K1319010_PsB3K3 master-plate (clone#1) in 5 mL LB-medium, each. The liquid cultures were prepared in order to create cryo-stocks from K1319010-PsB3K3. Kanamycin was added to the liquid cultures as antibiotic.
+
-
 
+
-
*At 18:00 [[User:PatrickO|Patrick]] prepared a master-plate (LB+C) and corresonding liquid cultures from 6 clones of E.coli NEB10B k1319021-psB1C3. Liquid cultures and master-plate were incubated at 37 °C.

-
*At 23:30 [[User:PatrickO|Patrick]] prepared liquid from K1319025-psB3K3 clones #7, #8 and #9 in 5 mL LB-medium. Kanamycin was used as antibiotic and the cultures were incubated at 37 °C.
