Abstract: RT-PCR was used to study the expression of heat-shock 10 kDa protein.The results showed that there were two different HSP transcriptons of varied sizes in Homo liver cancer SMMC-7721 and Mus NS0.One HSP cDNA was composed of 312 bp(named HSPE1-1) and held 99% homology with HSPE1 mRNA reported(NM-002157).The other HSP gene cDNA was consisted of 313 bp(named Hspe1-1) and had 97% homology with Hspe1 mRNA reported(NM-008303).The homology between HSPE1-1 and Hspe1-1 was 92% in nucleotide sequence and 97% in amino acid sequence.Prokaryotic expression plasmids pET-28a-HSPE1-1 and pET-28a-Hspe1-1 for producing HSPE1 and Hspe1 proteins were constructed successfully.Its molecular weight was 14 kDa.Anti-His6 monoclonal antibody was used to demonstrate the identity of the proteins in Western Blot.The corresponding proteins were obtained after purification by Ni-NTA chromatography.The purified corresponding proteins would be helpfulin further studies of their molecular structure,biological function and clinical application.

Key words: Heat-shock 10 kDa protein ( Hsp10) , Homo sapiens heat shock 10 kDa protein 1 ( chaperonin 10) ( HSPE1) , Mus musculus heat shock protein 1 ( chaperonin 10) ( Hspe1) , Gene cloning, Protein expression
