Protocols

(estimated time: 2 hours)

Prepare agarose gel in 1x TBE buffer
Add ethidium bromide (using gloves and face mask for your safety):
- 1 µl in the small size agarose gel (70 ml)
- 2 µl in the middle size agarose gel (150 ml)
- 4 µl in the big size agarose gel (250 ml)
Cast the gel, insert the well-forming comb and let it polymerize
Add the loading buffer to each sample
Load the samples and 8 µl of marker
Set to 70-100 volts and electrophorese for the required amount of time
Use UV-light to look at the bands
Take a picture of the gel, if needed (not when bands have to be cut!!!)
