Fig. (6) VVL and PNA stained after polyacrylamide gel electrophoresis. A) Polyacrylamide gel stained with Coomassie blue; the same amount BSA (lane 1), rpLF (lane 2, indicated by arrow) and bLF (lane 3) was subjected to SDS-PAGE and stained with Coomassie blue. Lane M, molecular mass markers. B) Stained with VVL; the same protein samples stained with VVL. The arrow indicates rpLF. C) Stained with PNA; the same protein samples stained with PNA. The arrow indicates rpLF.
