The present invention generally relates to method for preparing a biological sample for use in an immunolabeling process. The invention also relates to corresponding kits for use in the immunolabeling process.

The present invention generally relates to method for forming an immunolabeling complex, the immunolabeling complex comprising a labeled monovalent biotin-binding composition. The invention also related to the use of the antibody-reporter molecule complex for detecting a target in a sample.

The present invention may provide phosphor-integrated nanoparticles whose precipitation and/or aggregation, particularly aggregation can be inhibited upon carrying out immunostaining therewith and which can thus be used for staining even after long-term storage without requiring a complicated operation, the phosphor-integrated nanoparticles preferrably maintaining excellent performance, such as staining properties, even after long-term storage. The phosphor-integrated nanoparticles of the present invention have an average sphericity (f) of 0.80 to 0.95 and preferably have an average circumference ratio (R) of 0.50 to 0.95. More preferably, the matrix of the particles contains an organic compound, the phosphor-integrated nanoparticles have an average particle size of 300 nm or less, and a biological component-binding molecule is bound on the particle

The present invention provides a novel target analysis chip and analysis method for directly detecting a target such as a microRNA without performing PCR.

Provided herein are improved methods for diagnosing allergy in a subject using designed ankyrin repeat proteins (“DARPins”), and kits for use in such methods. Also provided herein are novel DARPins and methods of use thereof.

Provided herein, in some aspects, are methods of imaging molecules without a microscope or other specialized equipment, referred to herein as “microscope-free imaging (MFI).” Herein, “molecular instruments” (e.g., DNA-based and protein-based molecules) are used, instead of microscopes, in a “bottom-up” approach for inspecting molecular targets.

[Object] To provide a novel examination method for a cancer treatment effect, screening method for a peptide for a cancer vaccine, and peptide and composition for inducing an immune response against cancer. [Solving Means] Provided are an examination method for a cancer treatment effect and a screening method for a peptide for a cancer vaccine each including detecting an antibody against a cancer/testis antigen or an anti-p53 antibody in a sample. It is suitable that an anti-XAGE1 antibody (IgG and/or IgA) be detected, or an anti-NY-ESO-1 antibody (IgG) be detected. Also provided are a novel peptide and novel composition for inducing immune responses against cancer.

Methods, compositions and kits useful in the detection, assessment, diagnosis, prognosis and/or treatment of brain injuries, especially mild traumatic brain injury (mTBI) or concussion, are based upon detection of changes in levels of certain protein biomarkers in a subject undergoing testing, or upon detection of changes in levels of certain protein biomarkers in conjunction with neuroimaging analyses to detect changes in vascular or blood brain barrier (BBB) permeability in the brain, or to detect damage to fiber tracts in the brain, in which changes in biomarker levels correlate with detection of changes in BBB permeability or in brain fiber tract or white matter damage in a subject with brain injury such as mTBI or concussion.

Provided herein are methods for detecting neutralizing antibodies to leptins, including metreleptin, as well as identifying subjects having such neutralizing antibodies.

The present disclosure is directed to human monoclonal IgE antibodies, and IgG antibodies engineered therefrom. Such engineered antibodies can be used to blunt pathologic IgE responses in subjects, such as in the treatment or prevention of allergies.
