| Abstract: | GST-hSef fusion protein was expressed in E.coli and purified, which was used for the preparation of polyclonal antibody from rabbit. hSef expressed in COS-7 cells showed molecular weight of 80 kD and 100 kD respectively, slightly larger than that from in vitro translation result, which inferred the glycosylation at the potential N-linked glycosylation sites in the extracellular domain. Northern blot showed hSef mRNA was mainly expressed in human kidney and testis tissues. RT-PCR analysis showed a wide spread expression pattern in several cell lines. Immunohistochemical analysis revealed high expression level of hSef protein in kidney, testis and the corresponding carcinoma tissues.The results provide foundation for further study of Sef's function in pathophysiological conditions. |
