We will be using a Bio-Rad Mini Protean system with pre-cast Mini Protean TGX gels. The manual for this system can be found [http://www.bio-rad.com/webroot/web/pdf/lsr/literature/Bulletin_1658100.pdf here] We will be running SDS-PAGE followed by gel development with Coomassie Blue staining. | |||
Below is a short description of how we will proceed. Please refer to the manual for more detailed instructions | |||
# Prepare the Gel and Assemble the Electrophoresis Cell | |||
## Remove comb and tape from the gels | |||
## Rinse the wells with running buffer | |||
## Load 18uL of ladder and sample in the wells | |||
# Perform electrophoresis | |||
## Run for 30 minutes at 200V (I need to make sure our power source can do this) | |||
# Develop/Stain your gel | |||
## Place gel in Fixative Solution for 30 minutes | |||
## Place gel in Stain Solution for 1 hour | |||
## Place gel in Destain Solution for 15 minutes | |||
### Repeat this step with fresh destain solution 1 more time | |||
