(A) SDS-PAGE analysis of the purified MTFK. Molecular mass markers are shown in the left lane. The active fraction of the TSK gel Ether-5PW column is shown in the right lane. (B) Elution profile of the purified MTFK on TSK gel G2000 SWxl. The data above the chromatogram gives the estimation of the molecular mass (M.W.) of MTFK. The molecular mass standards (open circles) are 67, 43, 25, and 13.7 kDa, respectively. MTFK is shown as the solid circle. BSA, bovine serum albumin.
