  • Title: [Prokaryotic expression and purification of different truncated protein of Mayven].
    Author: Liu F, Wang Y, Liu X, He J.
    Journal: Sheng Wu Yi Xue Gong Cheng Xue Za Zhi; 2008 Dec; 25(6):1401-4. PubMed ID: 19166218.
    Abstract:
    To understand the function of Mayven and investigate the pathogenesis of multiple sclerosis, the gene sequences of different truncated Mayven were amplified from the gene library of human brain. These truncated fragments, including fragment P1 (1-902 bp), fragment P2 (1-523 bp), fragment P3 (507-182 bp) and fragment P4 (887-1782 bp), were cloned into pGEX-4T-2 vector to construct recombinant plasmids. The recombinant plasmids were transformed into E. coli BL21(DE3) and induced to express by IPTG. The expressed proteins were detected by SDS-PAGE and Western blot, and were purified by GST purifying system. The results showed that recombinant express vectors of different truncated GST-Mayven were successfully constructed and were expressed in soluble form protein induced by IPTG. The fusion proteins have good reactivity to GST antibody. The construction of recombinant express vectors of different truncated GST-Mayven lays a basis for further function study on Mayven.
