But in this expression system, induction temperature and time were the key parameters, and the expression amount of His-TIMP-2 in E. coli increased with the increase of induction temperature. The purified and refolded fusion protein could effectively inhibit the activity of matrix metalloproteinases expressed by human lung cancer A549 cells. The acquisition of active fusion protein lays a foundation for further study of the function and mechanism of human TIMP-2, and is of great significance for tumor therapy.Glypican-3 (GPC3) is a key member of Glypican family and plays an important role in the development, angiogenesis and metastasis of hepatocellular carcinoma (HCC). Most HCC overexpresses GPC3, but GPC3 is hardly detected in normal adult liver and benign liver lesions, so it is regarded as a highly specific diagnostic marker and an ideal therapeutic target for HCC. In this study, we cloned the heavy and light chain variable region gene from the monoclonal antibody targeted to GPC3 screened in the previous stage, and linked it with a segment of flexible peptide (Linker) to obtain the single chain antibody against GPC3. The single chain antibody gene was cloned into vector for prokaryotic expression and purified to obtain high purity protein. Detection shows that the single-chain antibody produced by us has the same binding activity with the full-length antibody, and can accurately target the tumor site of Huh7 tumor-bearing model mice after coupling Cy5.5 fluorescence, suggesting that the single-chain antibody has the potential to realize multi-directional liver cancer precise surgical navigation under the guidance of a probe.Amygdalus pedunculata Pall. is one of the 12 important woody oil crops in China. In this study, we determined the complete chloroplast genome sequence of A. pedunculata Pa
