Monday
This is the first day of the iGEM lab training. We were given several important tips by Wendy to begin with, and then throughout the day, we had to familiarise with basic lab techniques, e.g. the use of pipettes.

Wet Lab techniques practice
Aims
The aim of today's Lab training session was to practice aseptic technique and wet lab techniques such as streak plating and broth culture.
Equipment list
For today's session we needed:
- Agar plates
- Pipettes
- Wire loops
- E.coli (from a colony)
- LB broth
- Bunsen burner
- Conical flasks
- Orbital shaker
List of techniques
- Made broth culture
- Familiarised with using pipettes of different sizes
- Mini-Prep introduction for Tuesday.
- Used balance and made LB broth.
The biobrick BBa_J04450's prefix and suffix were identified. They are EcoRI and PstI respectively.
Tips
- Use aseptic technique: Treat everything as a pathogen!
- Work around the bunsen burner.
- Use a control.
- Clean the bench at the end of the day!
- Heat the wire loop from the middle to the tip.
- Keep plates upside down.
- Keep lids off for as short a time as possible.
- Loosen all the tops off the vessels before you start.
- Flame tops of bottles lightly.
- Colony plates should be labelled (name of culture, our initial, date) at the base in order to prevent condensation.
- For individual clony extraction, steak across a few times in different directions in order to dilute
- Wear gloves, especially when working with DNA, PCR etc. However, never wear gloves when working near a flame
Streak plating
Star plate streaking student, Deena, shows off how it is to be done!
Set up culture for minipreps
5 ml culture with E.coli from a single colony grown over night. Tomorrow we will harvest the DNA.
Outcome
We learnt aseptic technique and some basic wetlab techniques. As you can see in the picture above our streak plates worked.
