Fractionation of C. majus whole plant extract on a heparin column. Top: Absorbance at 280 nm—blue line—indicates protein content in fractions. Red lines and numbers represent fraction numbers. Middle: In-gel DNase assay zymography of protein fractions with high nucleolytic activity. Band 1A of ca. MW 33–35 kDa was cut, and MLP presence was confirmed by MS/MS. Bottom: Protein profiles of each fraction in SDS-PAGE stained with silver. Band 1B of ca. MW 36 kDa was cut from the gel, and MLP presence was confirmed by MS/MS.
