4 results about "Hypervariable region" patented technology

Provided herein are libraries containing polynucleotides, where one of the polynucleotides encodes an antibody heavy chain with specific hypervariable regions HVR-H1 and HVR-H2. Further provided herein are libraries containing polynucleotides encoding a plurality of unique antibodies, wherein each antibody comprises a heavy chain variable region and a light chain variable region. Also provided are antibodies, polypeptide libraries, vector libraries, cells, non-human animals, antibody heavy chains, methods of making an antibody library, kits, and methods of generating a bispecific antibody related thereto.

This application describes a technology relating to treating neurofibromatosis type 1 and particularly, but not exclusively, to compositions and methods for gene replacement therapy treatments of patients having NF1-related tumors, for example, new recombinant adeno-associated virus vectors comprising a neurofibromatosis type 1 GAP-related domain fused to a Ras hypervariable region and use thereof to treat neurofibromatosis type 1.

This invention relates to the field of biological protein application technology, and discloses the application of flagellin hypervariable region H as an intramolecular adjuvant in vaccine preparation. The amino acid sequence of flagellin hypervariable region H is shown in SEQ ID NO.3, and the nucleotide sequence of the gene encoding flagellin hypervariable region H is shown in SEQ ID NO.4. This invention also discloses an expression cassette, recombinant vector, recombinant cells, or recombinant bacteria containing the gene encoding flagellin hypervariable region H. This invention uses the aforementioned flagellin hypervariable region H as an intramolecular adjuvant in vaccine preparation. This invention connects flagellin hypervariable region H to an antigenic epitope to obtain a fusion protein. Compared with existing technologies, the solubility and activity of the fusion protein are improved. Simultaneously, this invention overcomes the expression form of inclusion bodies in existing E. coli expression systems, eliminating the need for subsequent refolding and assembly, thus simplifying the vaccine preparation process.

The application discloses a kind of paragallinarievaccines and preparation method thereof, the paragallinarievaccines include A type paragallinarie, B type paragallinarie and C type paragallinarie HMTp210 hypervariable region protein and avian pathogenic escherichia coli ghost.The application uses three serotypes HMTp210 hypervariable region recombinant protein and avian pathogenic escherichia coli ghost (especially O78 type avian pathogenic escherichia coli ghost) in combination, synergistically enhances humoral and cellular immunity, provides more broad-spectrum protection, while reaching the protection effect equivalent to white oil adjuvant, significantly improves injection safety, avoids the granuloma and other side reactions of white oil adjuvant, realizes the technical goal of "equivalent protection, better safety".
