β¦ Synopsis
A rapid procedure for the purification of fructose-l,6-bisphosphate aldolase from spinach chloroplasts is presented which involves two steps; precipitation of bulk protein with polyethylene glycol and partitioning of remaining soluble protein in aqueous two-phase systems. A 94% pure preparation is obtained within 6h with a yield of 19%. A marked difference in the partition behaviour of the aldolase activity from whole leaf tissue suggested that the procedure is less efficient when leaf extract is used as starting material.
