title: Construction of eukaryotic expression vector of thrombospondin-1 type I repeat sequence.
abstract: OBJECTIVE
  To construct eukaryotic expression vector of thrombospondin-1 type I repeat sequences.
  
  
  METHODS
  Thrombospondin-1 type I repeat sequence gene was amplified from human fetal lung tissue by reverse transcriptase-PCR (RT-PCR) to construct both recombinant clone vector and expression vector through coupling reaction, followed by transforming these vectors into E.coli DH5alpha. The positive clones were selected for verification by double enzyme digestion and sequence analysis.
  
  
  RESULTS
  The expected amplification product, thrombospondin-1 type I repeat gene sequence, was acquired by RT-PCR, which had a consistency up to 99% with the sequence from the GenBank.
  
  
  CONCLUSIONS
  The eukaryotic expression vector PcDNA3.1(+)/TSP-1 type I repeat sequence was successfully constructed.
