Experimental details: Immunofluorescent analysis of Thrombospondin (green) showing staining in the secretion of HeLa cells. Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with a Thrombospondin monoclonal antibody (Product # MA5-13398) in 3% BSA-PBS at a dilution of 1:100 and incubated overnight at 4 ºC in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjugated secondary antibody in PBS at room temperature in the dark. F-actin (red) was stained with a fluorescent red phalloidin and nuclei (blue) were stained with Hoechst or DAPI. Images were taken at a magnification of 60x.

Sigma His-Select HF nickel affinity gel was used to capture His-tagged Efb- or Efb-N-interacting proteins from platelet lysates. Affinity precipitates were separated by SDS-PAGE and immunoblotted for integrin alphaIIb, P-selectin, multimerin-1, fibronectin, thrombospondin-1 (indicated by Thrombosp.-1 ), and His tag (to confirm Efb/Efb-N expression and immobilization). Immunoblots shown here are representative of those from three independent experiments. -ve , negative control; PD , pulldown. B , SPR data confirm the direct interaction of Efb and P-selectin. Recombinant P-selectin-Fc immobilized on COOHV-coated SensiQ TM sensor chips was treated with increasing concentrations of Efb (100 n m ( brown ), 300 n m ( purple ), and 2.8 mu m ( green )). All experiments were performed using the SensiQ TM Pioneer FE SPR platform (SensiQ Technologies). Experimental data were fit using the Qdat data analysis software. Curves were fitted using a least squares fitting algorithm. RU , response units.
