Photograph of clots after 20 minutes. Clot retraction experiments were performed as described in Fig 3A and a photograph of the tubes containing the clots was taken after 20 minutes. The photograph is representative of the results observed in all four experiments performed. Tubes: 1, normal recombinant fibrinogen; 2, recombinant Aα D97E fibrinogen; 3, recombinant Aα D574E fibrinogen; 4, recombinant Aα DE2/γ 407 fibrinogen.
