Abstract:
Objective: To clone cDNA of enamel matrix serine proteinase (EMSP1) encoding mature protein from mouse dental germs. Methods: Total RNA was isolated from developing incisors and molars of 7 days mouse pups and reverse-transcribed into cDNA. Two pairs of specific primers was designed to obtain the desired gene by Touchdown PCR and Nested PCR. The segment was inserted into Vector pMD-18T, and recombined vectors was transformed into E.coli JM109.The positive clone was chose and analysed by restriction endonuclease mapping and DNA sequencing. Results:700 bp of cDNA of mouse EMSP1 was sueccessfully cloned from mouse tooth germs tissue. The sequence was consistent with that displayed in PubMed. Conclusion:The mouse EMSP1 cDNA encoding mature protein is obtained for further study.
