#Elute with ~5 mL room temp. elution buffer, collecting 10 x ~0.5 mL fractions. Check fractions for protein with Bradford assay
#Combine fractions with protein and dialyse O/N into 200 mL PBS in 50% glycerol (will concentrate sample ~4X) or other desired buffer
#Measure protein concentration ([[Bradford Assay]] or [[Quantification by Absorbance at 280nm]]; concentrate if necessary and store at -20)
#Analyze uninduced and induced cells (0.5 mL culture resuspended in 100 uL 2X SDS), lysate (5 uL in 2X), unbound (5 uL in 2X) and purified protein (0.5-10 ug) by SDS-PAGE
