#Do a bradford assay using 1 uL of clarified lysate and label tube with correct concentration (see [[Bradford Assay]])
#Follow Protein Lysate instructions for Bradford Assay (see [[Bradford Assay]])
#Prepare samples for gels by adding 800 ug protein to a final volume of 200 uL of lysis buffer.  Add 200 uL of 2X loading buffer with B-ME to each lyaste.  This will generate a 2 mg/mL protein solution in SDS Loading Buffer
