    摘要: This disclosure pertains to the technical field of antibodies, and discloses PD-L1 nanobodies, preparation methods and uses thereof; two primers are designed and synthesized; a sufficient amount of target products is amplified by PCR to carry out replacement enzyme digestion; target fragments are ligated to vectors, transformed, and screened to obtain clones; proteins are identified and expressed; antibody library is constructed; M13 phage display system is selected to display VHH antibody library, which consists of pMECS phagemid vector, E. coli TG1 and M13K07 helper phage. In the phagemid vector pMECS of this disclosure, the sequence before the Pst I restriction site is the coding sequence of the pelB secretion signal peptide and part of the amino acids in the first framework region of the antibody; the pelB signal peptide can guide the secretion of the subsequent polypeptide to the periplasmic cavity; Not I restriction site is followed by the coding sequence of HA and 6×His tag, which can be used for purification or detection of fusion protein.

    摘要: A nanobody and its application based on SARS-CoV-2 S protein are provided, and the present disclosure relates to biomedical technology. The present disclosure chooses the Spike S1+S2 ECD of SARS-CoV-2 as a target, and screens the nanobody against of SARS-CoV-2 by using a nanobody library. After an ELISA test, the Spike S1+S2 ECD target of SARS-CoV-2 can be specifically identified while a SPIKE RBD target is identified, and a binding signal is relatively strong. The corresponding nanobody sequence is constructed into a prokaryotic expression vector for expression and purification to express the target nanobody successfully. After the purification, the purity is greater than 90%. The ELISA test of VHH nanobody showed that the purified nanobody has higher affinity to the two targets.

    摘要: Disclosed is a mowing method for compensatory growth of a desert plant Anabasis aphylla, falling into the field of plant mowing methods. The mowing method includes the following steps: step 1: mounting a frame body on movable equipment; step 2: driving the movable equipment to move a device to a working area; and step 3: intermittently operating the movable equipment to allow an area formed by a push plate I, baffle plates II and a push plate II to be exactly opposite to a suitable number of Anabasis aphylla. The present disclosure is to provide a mowing method for compensatory growth of a desert plant Anabasis aphylla to solve the technical problem, facilitating the mowing of Anabasis aphylla.

    摘要: The application belongs to the technical field of animal or human antibodies, and discloses a TIM-3 nanobody, a preparation method thereof and use thereof. The nanobody is a TIM-3 nanobody with sequence of SEQ ID NO:1. TIM-3 antigen is a transient transfection expression by mammalian cells. TIM-3 antigen is used to screen the nanobody library repeatedly, specific phage of nanobody is obtained, and the target fragment is conducted sequencing. The application uses the HEK293 cell line to express antigen. Using the mammalian expression system to express human protein may maximumly guarantee the original structure of the protein, guarantee the protein to have a post-translational modification and specific modifications of eukaryotic proteins such as glycosylation, which makes the obtained protein have high activity. This method maximizes the original structure and activity of the protein; the nanobodies screened by the application can efficiently and specifically bind to the target.
