In our experiments, we often re-used protocols for basic experimental steps. For a better overview, we split our protocols into four categories:
-
== LB medium ==
+
-
# weight components
+
-
::* '''5&nbsp;g/L NaCl'''
+
-
::* '''10&nbsp;g/L tryptone'''
+
-
::* '''5&nbsp;g/L yeast extract'''
+
-
::* (15&nbsp;g/L agar for plates)
+
-
# fill up to 1&nbsp;L with deionized water
+
-
# '''mix well''' by shaking
+
-
# autoclave
+
-
## autoclaving tape, caps slightly unscrewed
+
-
## base of the pot has to be covered with deionized water
+
-
## close lid
+
-
## heat '''level 3 until the pressure valve opens'''
+
-
## reduce '''heat level to 1.5'''
+
-
## set timer to '''20 minutes'''
+
-
## turn heater off
+
-
## '''wait until the pressure valve retracts''' (30-45 minutes)
+
-
## open, close caps & shake
+
-
# for plates, wait until you can touch the bottle ('''<60&nbsp;°C''', clean bench!)
+
-
# add antibiotics (1&nbsp;µL/mL) and '''shake''' (gloves!)
+
-
== TB medium ==
+
* 2D Detection of IPTG & HSL
-
# components 1:
+
* Culture Media
-
::* '''4 ml/L glycerol'''
+
* Molecular Biological Methods
-
::* '''12 g/L tryptone'''
+
* Analytical Methods
-
::* '''24 g/L yeast extract'''
+
-
# fill up to 900&nbsp;ml with deionized water

-
# '''mix well''' by shaking

-
# autoclave
+
-
# components 2:
+
-
::* '''0.17 M KH<sub>2</sub>PO<sub>4</sub>'''
+
-
::* '''0.72 M K<sub>2</sub>HPO<sub>4</sub>'''

Protocols

In our experiments, we often re-used protocols for basic experimental steps. For a better overview, we split our protocols into four categories:

  • 2D Detection of IPTG & HSL
  • Culture Media
  • Molecular Biological Methods
  • Analytical Methods

To access the protocols, please click on the respective category panel below:
