title: [The cloning and sequencing of H-2Kk gene cDNA of 615 mice].
abstract: OBJECTIVE
  The purposes of this study were to clone and sequence the major histocompatibility complex type I (MHC I) molecular antigen recognizing gene (H-2Kk) of 615 mice, and to provide the functional gene for transgenic therapy.
  
  
  METHODS
  The 1.4 kb full-length fragment of H-2Kk gene complementary DNA (cDNA) was amplified from the total RNA of 615 mouse liver by using reverse transcription polymerase chain reaction (RT-PCR). The cDNA was inserted into PGEM3Zf(+) vector directionally, and the competent E. coli JM109 was transformed with the ligated product. The recombinant PGEM3Zf(+)-H-2Kk cDNA plasmid was obtained using restricted enzyme analysis of the transfectants. The complete sequence of 615 mouse H-2Kk cDNA was determined by using Sanger's method.
  
  
  RESULTS
  The sequences of 615 mouse H-2Kk cDNA were 99% similar with those of H-2Kk cDNA which were reported by other researchers, and the sequences encoding antigen recognizing regions (ARS) were identical with each other.
  
  
  CONCLUSIONS
  The authors cloned the MHC I molecular antigen recognizing gene (H-2Kk) of 615 mice successfully and got the functional gene of MHC I.
