Fibrinogen had no obvious effect on VSMC migration in scrape assay and on VSMC migration at random direction in Time-lapse microcinematography (P>0.05).
SDS-PAGE was used to detect the purity of target protein. A higher bioactivity of purified products was shown by the determination of dot-blotting assay and fibrinogen-clotting analysis.
