Fig. 7. Western blots of cobalt chelate gel column elution fractions. Recombinant caspase 6 (0.6 µg, left lane), 30 µl of the elution fraction from the control column, where caspase 6 was omitted (middle lane), and 30 µl of the elution fraction from the caspase 6-Co²⁺ column (right lane) were separated on a 10% NuPage gel and detected by western blot with anti-caspase 6, anti-B-crystallin or anti-A-crystallin antibodies.
