AI Article Synopsis
- - The study aimed to clone and express the PID domain of human DOC-2 (nDOC-2) in E. coli DH5alpha.
- - Researchers used RT-PCR to amplify the nDOC-2 cDNA from ovarian tissue, cloned it into a vector, and confirmed the expression of the protein using SDS-PAGE.
- - Successful expression of the PID domain in bacteria paves the way for future research on DOC-2's function and the development of antibodies against its protein.
Article Abstract
Aim: To clone the PID domain of human DOC-2 (nDOC-2) and express it in E.coli DH5alpha.
Methods: The cDNA fragment encoding the PID domain of nDOC-2 was amplified by RT-PCR from normal human ovarian tissue and cloned to pUC19. The DNA fragment from the pUC19-nDOC-2 digested with BamH I and EcoR I was ligated to the BamH I/EcoR I digested prokaryotic expression vector pGEX-4T-1.The expression of fusion protein was induced with IPTG and the expressed product was identified by SDS-PAGE.
Results: (1)The sequencing and endonucleases digestion analysis showed that the fragment of nDOC-2 gene was insert into vectors pUC19 and pGEX-4T-1;(2)SDS-PAGE showed the nDOC-2 gene had been expressed in E.coli DH5alpha.
Conclusion: The PID domain of nDOC-2 was expressed successfully in prokaryote, which makes preparation for further researching the function of DOC-2 and preparing antibodies to DOC-2 protein.
