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.
