Objective:To clone the DNA sequence coding the F3T7
generate the fused protein F3T7
and investigate its function. Methods:We constructed prokaryotic expression vector pET32a(+)-F3T7 by subcloning technique
then fusion protein F3T7 was expressed and purified by affinity chromatography.and its activity of inhibiting the perliferation of HUVEC was assayed by MTT
then FITC was adopted to mark F3T7 to test its affinity with HUVEC
and its anti-angiogenses was detected by CAM. Results:We primarily certified that the fusion protein F3T7 selectively bound to HUVEC
inhibited its proliferation
and showed anti-angiogenic activity.Conclusion:F3T7 could have the abilities of binding to HUVEC and anti-angiogenesis
