Provided are a method for screening for nanobodies and a corresponding system. The method uses polymerase chain reactions and cDNA 5′ end rapid amplification technology to screen for and obtain nanobodies. The experiment cycle requires only approximately 21 days.

In one aspect, the invention relates to a method suitable for administering protein therapeutic molecules orally, sublingually, topically, intravenously, subcutaneously, nasally, vaginally, rectally or by inhalation so as to avoid inactivation, by using VHH polypeptides derived from Camelidae antibodies. The invention further relates to the said therapeutic molecules. The invention further a method for delivering therapeutic molecules to the interior of cells. The invention further relates to anti-IgE therapeutic molecules. In one aspect, the present invention relates to a method wherein an immunoglobulin single variable domain (such as a Nanobody) and/or construct thereof are absorbed in pulmonary tissue. More particularly, the invention provides systemic delivery of an immunoglobulin single variable domain and/or construct thereof via the pulmonary route.

Chimeric Fc fusion polypeptides are provided, optionally including biologically active polypeptides for therapeutic use.

An antibody that specifically binds to a glucocorticoid-induced tumor necrosis factor receptor (GITR), an antibody fragment and a polymer thereof, and a conjugate and a fusion comprising the antibody or the antibody fragment are provided in the present invention. A nucleic acid encoding the antibody, the antibody fragment, the polymer, the conjugate and the fusion, a vector, and a host cell expressing the nucleic acid are also provided in the present invention. In addition, a composition comprising the antibody and the antibody fragment thereof, the polymer, the conjugate or the fusion, and use thereof in therapy and diagnosis are also provided in the present invention.

A system for inducing activity of immune cells, comprises a chimeric antigen receptor, a T cell receptor, and various combinations thereof.

The present invention relates to the field of biotechnology and provides monoclonal tri-specific binding molecules that specifically bind to human IL-17A, human IL-17F, and a human pro-inflammatory molecule (in particular, TNFα) with high affinity. The invention also relates to DNA constructs encoding said binding molecules, related expression vectors and methods of production, and methods of treatment using said binding molecules.

The present invention relates to methods for detecting analytes in a sample. The methods may also be used to determine the amount of analyte in the sample. The present invention also relates to antibody or antibody-like molecules and labelled antigens for use in these methods.

Provided herein are EpCAM binding proteins, pharmaceutical compositions comprising such proteins or fragments thereof, as well as nucleic acids, recombinant expression vectors and host cells for making such EpCAM binding proteins. Also disclosed are methods of using the disclosed EpCAM binding proteins in the prevention, and/or treatment diseases, conditions and disorders.

The present invention relates, in part, to agents that bind CD8 and their use as therapeutic and diagnostic agents. The present invention further relates to pharmaceutical compositions comprising the CD8 binding agents and their use in the treatment of various diseases, including, for example, cancers.

The present invention relates to unique CDR3 amino acid sequences, and to antibodies comprising said sequences. Also provided are therapeutic applications of said antibodies for use in treating or preventing influenza infection, diagnostic applications of said antibodies for use in detecting influenza virus, potency testing of influenza virus vaccines, and screening applications of said antibodies for use in designing a universal influenza vaccine.
