Abstract: Provided is an isolated antigen-binding protein, which can specifically bind to CD73 and includes at least one CDR in a heavy chain variable region VH, wherein the region VH includes an amino acid sequence as represented by SEQ ID NO: 49.

Abstract: Provided in the present application are an anti-PD-L1/TGF-? bispecific antibody and the use thereof. Specifically, provided in the present application is a bifunctional antibody, which comprises: (a) an anti-PD-L1 antibody or element; and (b) an anti-TGF-? antibody or element connected to the anti-PD-L1 antibody or element. The bifunctional antibody of the present application can simultaneously bind to TGF-? and PD-L1, thereby exerting a therapeutic effect on TGF-? and PD-L1-positive tumor cells.

Abstract: Provided is an isolated antigen-binding protein, capable of binding to CD73. The isolated antigen-binding protein contains HCDR3, and the HCDR3 comprises an amino acid sequences as shown in SEQ ID No.:3. Also provided are a preparation method for the antigen-binding protein, and an application of the antigen-binding protein.

Abstract: The present application provides an antibody targeting interleukin 36R, a preparation method therefor, and an application thereof. Specifically, the present application provides an IL-36R antibody having high affinity and high bioactivity. The antibody can bind to IL-36R with high affinity, and can block the binding between an IL-36R ligand (?, ?. ?) and the IL-36R and a signal path activated by the IL-36R ligand, thereby treating and/or preventing IL-36 related diseases.

Abstract: Provided is a separated antigen-binding protein. The antigen-binding protein comprises at least one CDR in a heavy chain variable region VH, and the VH comprises an amino acid sequence shown in SEQ ID NO: 55. Also provided are an anti-TIGIT antibody, and a preparation method and an application thereof. The antigen-binding protein can specifically bind with a TIGIT antigen to block the binding of TIGIT and a ligand thereof, and can be used for preparing drugs for preventing or treating TIGIT-related diseases.
