Protein purification and characterization. (a) SDS–PAGE showing undigested (lane 2) and thrombin-digested (lane 3) samples. Lane 1 contains molecular-mass markers (labelled in kDa). (b) SEC–MALLS analysis. The thin line corresponds to the absorbance at 280 nm. The thick line below the absorbance peak corresponds to the molecular weight calculated for the eluted protein. |
