The present invention relates to novel peptides derived from Structural maintenance of chromosomes protein 1B (SMC1B), complexes comprising such peptides bound to recombinant MHC molecules, and cells presenting said peptide in complex with MHC molecules. Also provided by the present invention are binding moieties that bind to the peptides and/or complexes of the invention. Such moieties are useful for the development of immunotherapeutic reagents for the treatment of diseases such as cancer.

The present invention provides a sensitive and specific indirect homogeneous mobility shift assay using size exclusion chromatography to measure biologics such as vedolizumab and ustekinumab in a patient sample. The assays of the present invention are particularly advantageous for detecting the presence or level of biologics that target complex or large antigens including cell surface proteins, transmembrane proteins, heavily glycosylated proteins, and multimeric proteins, as well as antigens that cannot be purified, impure antigens, and partially or substantially purified antigens. The present invention also provides isolated soluble α4β7 integrin heterodimers and isolated soluble IL-12p40 monomers that are suitable for use in the indirect assays described herein.

In one aspect, the invention relates to a composition including a first polypeptide having the sequence set forth in SEQ ID NO: 1 and a second polypeptide having the sequence set forth in SEQ ID NO: 2. In one embodiment, the composition includes about 120 g/ml of a first polypeptide including the amino acid sequence set forth in SEQ ID NO: 1, 120 g/ml of a second polypeptide including the amino acid sequence set forth in SEQ ID NO: 2, about 2.8 molar ratio polysorbate-80 to the first polypeptide, about 2.8 molar ratio polysorbate-80 to the second polypeptide, about 0.5 mg/ml aluminum, about 10 mM histidine, and about 150 mM sodium chloride. In one embodiment, a dose of the composition is about 0.5 ml in total volume. In one embodiment, two-doses of the composition induce a bactericidal titer against diverse heterologous subfamily A and subfamily B strains in a human.

The invention provides an agent for preventing or treating a condition characterised by the presence of unwanted cells, the agent comprising: (i) a targeting moiety that is capable of targeting to the unwanted cells; and (ii) a T cell antigen, wherein the T cell antigen can be released from the targeting moiety by selective cleavage of a cleavage site in the agent in the vicinity of the unwanted cells.

A hybrid protein comprises a first domain comprising a sequence encoding a surface protein of an enveloped RNA virus and a second domain comprising a sequence encoding an ectodomain of a type 2 transmembrane domain protein, wherein the second domain is located at the C-terminal of the first domain. The hybrid protein or an mRNA encoding such protein can be used as a vaccine against the infection of the enveloped RNA virus.
