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 g/L NaCl'''
+
-
::* '''10 g/L tryptone'''
+
-
::* '''5 g/L yeast extract'''
+
-
::* (15 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 °C''', clean bench!)
+
-
# add antibiotics and '''shake''' (gloves!)
+
-
== TB medium ==

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:
