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&nbsp;mL/L glycerol'''
+
* Molecular Biological Methods
-
#: '''12&nbsp;g/L tryptone'''
+
* Analytical Methods
-
#: '''24&nbsp;g/L yeast extract'''
+
-
# Fill up to 900&nbsp;mL with deionized water
+
-
# '''Mix well''' by shaking
+
-
# Autoclave
+
-
# Components 2:
+
-
#: '''0.17&nbsp;M KH<sub>2</sub>PO<sub>4</sub>'''
+
-
#: '''0.72&nbsp;M K<sub>2</sub>HPO<sub>4</sub>'''
+
-
# Dissolve in 100&nbsp;mL deionized water and sterilize it by passing it through a filter
+
-
# After autoclaving and cooling down, add sterile phosphate solutions

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:
