An object of the present invention is to provide an immunological detection method comprising carrying out an immunoreaction using an antibody to Mycoplasma pneumoniae protein P30, in which Mycoplasma pneumoniae is detected with high sensitivity. Provided is an immunological detection method for Mycoplasma pneumoniae using an antibody to Mycoplasma pneumoniae protein P30, the method comprising carrying out an immunoreaction in the presence of a polyoxyethylene alkyl amine. The immunological detection method that uses immunochromatography is also provided.

Mycobacterial-specific biomarkers and methods of using such biomarkers for diagnosis of mycobacterial infection in a mammal are disclosed.

[Problem] An object of the present invention is to provide a detection marker that can simply and rapidly detect Mycoplasma pneumoniae, which is a pathogen of mycoplasma pneumonia, at a high sensitivity, a specific antibody against the marker, and also an immunological detection method and a kit containing the antibody. [Solution] Infection with Mycoplasma pneumoniae can be rapidly and specifically diagnosed by producing an antibody specifically reactive to P30 protein of Mycoplasma pneumoniae and performing an immunological assay using the P30 protein as a detection marker. The present invention enables easy and rapid detection of Mycoplasma pneumoniae and diagnosis of infection with the bacteria at a hospital or the like without need of specialized instruments or skilled techniques.

This disclosure presents an Enzyme-Linked Immunosorbent Assay (ELISA) for the selective detection of anti-Mycoplasma hyorhinis IgG in porcine serum, which may contain antibodies specific to multiple other Mycoplasma spp.

Mycobacterial-specific biomarkers and methods of using such biomarkers for diagnosis of mycobacterial infection in a mammal are disclosed.

Provided are methods of detecting a marker for active tuberculosis, and a portable device for carrying out a method of detecting a marker for active tuberculosis. Also provided is a system for carrying out a method of detecting a marker for active tuberculosis, a method for pre-treating a sample stream from a human or animal suspected of having active tuberculosis, a system for pre-treating a sample stream from a human or animal suspected of having active tuberculosis and kits for performing said methods.

Disclosed are methods and systems for analyte detection in a sample and more particularly, a biological sample. Methods and systems particularly relate to differentiating and/or identifying cell types in biological samples, such as blood samples, by adding antibodies specific to predetermined CD antigens. Other methods and systems relate to controlling the dynamic range of an assay for analyte detection.

The present invention provides a novel glyceroglycolipid produced by Mycoplasma pneumoniae. The glyceroglycolipid can be used as a diagnostic marker for a disease caused by Mycoplasma pneumoniae.

The invention relates to certain methods for the determination of an antigen content of a first antigen in a mixture comprising two or more antigens. The invention also relates to a potency test for an antigen in a combination vaccine. The method allows the determination of the antigen content in a mixture additionally comprising antibodies that are capable of binding with the antigen.

The present invention is intended to provide an immunochromatographic analyzer that enables a quick and easy, high-sensitivity detection of Mycoplasma pneumoniae, and thus more reliable and faster diagnosis of mycoplasma pneumonia. The immunochromatographic analyzer according to the present invention is for detecting Mycoplasma pneumoniae, and includes a sample adding section, a label-substance retaining section, a chromatographic medium section having a detection section, and an absorbing section. The label-substance retaining section and the detection section contain an antibody that strongly recognizes domain III of P30 protein of Mycoplasma pneumoniae consisting of the amino acid sequence of SEQ ID NO: 2.
