Ligation and gel electrophoresis
Chia-Hsien Shih
Abstract
This protocol is used for ligation of circular probe
Steps
Preparation
Dilute linear DNA into 10µM
Dilute T4 ligation primer into 10µM
Protocol of Ligation
Add 11µL
of RNase-free water into a eppendorf
Add 3µL
of 10X T4 Ligase buffer
Add 9µL
of 10µM T4 ligation primer
Add 3µL
of 10µM linear DNA
Add 4µL
of T4 Ligase
Spin down after vortex
Incubate for 4h 30m 0s
at 26Room temperature
Protocol of Gel Electrophoresis
Put 2% agarose gel into the electrophoresis tank.
Prepare 0.5X TAE buffer ( add 3.5mL
50X TAE buffer and 350mL
ddH2O and mix them), then pour into the electrophoresis tank. Make sure the gel is soaked into the buffer completely.
Take 5µL
of marker and load it in the first well.
Take 1µL
of 6X loading dye and drop on the parafilm separately, pipetting dye with 5µL
of sample
Load samples into each well
Run gel at a constant voltage of 100V for0h 30m 0s
at room
temperature
After gel electrophoresis, put the gel into gel reading machine and report the result.
