Expression, Purification and Bioactivities Analysis of Recombinant Active Peptide from Shark Liver
The Active Peptide from Shark Extra Handsets Liver (APSL) was expressed in E.coli BL21 cells.The cDNA encoding APSL protein was obtained from shark regenerated hepatic tissue by RT-PCR, then it was cloned in the pET-28a expression vector.The expressed fusion protein was purified by Ni-IDA affinity chromatography.SDS-PAGE and HPLC analysis showed th
