 * 1) Express from BLR (pACYC-derived plasmid) at RT for 3 hours post-induction (induce at OD = 0.8 after cooling to RT for 25 mins)
 * 2) Lyse in 20 mM Hepes, 400 mM NaCl, 100 mM KCl, 20 mM Imidazole, 10% glycerol pH 7.6
 * 3) Lysozyme + french press with PMSF (generates foam in french press
 * 4) Spin down, add sup to 4 mL Ni-slurry
 * 5) 2 washes with lysis buffer+PMSF on bench, add to column
 * 6) 3x washes in column, with 1 wash used to resuspend the column
 * 7) 0.5 mL elutions with lysis buffer - PMSF + 250 mM Imidazole
 * 8) pool fractions by bradford
