*Protein Markers, we use SeaBlue Plus2 from Invitrogen (cat #LC5925)
*Nitrocellulose, we use BioRad 0.45 um membrane from a roll (cat #1620115) and cut to the size of a gel
*Filter Paper, we use BioRad extra thick paper (cat 1703966)
*Transfer Buffer (200 mL Methanol, 100 mL 10X [[ Transfer Buffer ]] to final 1L volume)

## Use a prepared 4-12% tris gel (in the 4 degree). Remove it from the packaging, remove the white strip of tape from the bottom back, and gently pull the comb out and rinse with water.
## Use a prepared gel (in the 4 degree). Remove it from the packaging, remove the white strip of tape from the bottom back, and gently pull the comb out and rinse with water.  Pick a percent gel based on your expected protein size.
##Load into gel tank. Fill with SDS page Running buffer (1X) to the fill line in the front and halfway up the back
