The present invention relates to engineered multivalent and multispecific binding proteins, methods of making, and specifically to their uses in the prevention and / or treatment of acute and chronic inflammatory and other diseases.

The present invention discloses bispecific antibodies comprising two antibody variable domains on a single polypeptide chain, wherein a first portion of the bispecific antibody is capable of recruiting the activity of a human immune effector cell by specifically binding to an effector antigen on the human immune effector cell, the first portion consisting of one antibody variable domain, and a second portion of the bispecific antibody specifically binding to a target antigen other than the effector antigen, the target antigen on a target cell other than the human immune effector cell, the second portion comprising one antibody variable domain.

The invention provides comprising variant amino acids in CDRs of antibody variable domains. These polypeptides provide a source of great sequence diversity that can be used as a source for identifying novel antigen binding polypeptides. The invention also provides these polypeptides as fusion polypeptides to heterologous polypeptides such as at least a portion of phage or viral coat proteins, tags, and linkers. Libraries comprising a plurality of these polypeptides are also provided. In addition, methods of and compositions for generating and using these polypeptides and libraries are provided.

The invention provides a dual-specific ligand comprising a first immunoglobulin variable domain having a first binding specificity and a complementary or non-complementary immunoglobulin variable domain having a second binding specificity.

Provided are concentrated preparations comprising single immunoglobulin variable domain polypeptides that bind target antigen with high affinity and are soluble at high concentration, without aggregation or precipitation, providing, for example, for increased storage stability and the ability to administer higher therapeutic doses.

The invention provides polypeptides comprising a variant heavy chain variable framework domain (VFR). In some embodiments, the amino acids defining the VFR form a loop of an antigen binding pocket. In an embodiment, the polypeptide is a variable domain of a monobody and has a variant VFR. The polypeptide may optionally comprise one or more complementary determining regions (CDRs) of antibody variable domains. In an embodiment, the polypeptide is a variable domain of a monobody and has a variant VFR and one or more variant CDRs. Libraries of polypeptides that include a plurality of different antibody variable domains generated by creating diversity in a VFR, and optionally, one or more CDRs are provided and may be used as a source for identifying novel antigen binding polypeptides that can be used therapeutically or as reagents. The invention also provides fusion polypeptides, compositions, and methods for generating and using the polypeptides and libraries.

The present invention relates to engineered multivalent and multispecific binding proteins, methods of making, and specifically to their uses in the prevention and / or treatment of acute and chronic inflammatory and other diseases.

A bispecific antibody specifically binding to the two targets human CD3ε and human BCMA, wherein the variable domains of one antibody portion are replaced by each other, and characterized in that the binding of said antibody is not reduced by APRIL and not reduced by BAFF, said antibody does not alter APRIL-dependent NF-κB activation, BAFF-dependent NF-κB activation, and does not alter NF-κB activation without BAFF and APRIL is useful as a therapeutic agent.

A mutant Fab fragment of the 13B8.2 anti-CD4 antibody that binds a CD4 molecule and includes a mutation of at least one residue in a position situated in the VH variable domain of the heavy chain and / or in a position situated in the Vκ variable domain of the light chain.

An iris identification method and system, which divide an iris image, which is acquired for personal identification, into a plurality of equal / unequal and multiscale regions, generate a corresponding code corresponding to the respective regions, organizing codes into a database, generate a code at the time of authentication in the same manner, and identify a person by comparing this code with the codes stored in the database, thus improving identification speed and rate.
