Described herein are methods for preparing T cells, including isolating CD8+ T cells from a blood sample obtained from a patient or a donor, culturing the isolated CD8+ T cells in the presence of at least one cytokine, contacting the cultured CD8+ T cells with a multimer containing a target peptide in a complex with an MHC molecule and with at least one binding agent that binds to a T cell surface molecule, in which the multimer is labelled with a first detectable agent and the binding agent is labelled with a second detectable agent, sorting the contacted CD8+ T cells to collect the sorted CD8+ T cells that are detected positive for the first and the second detectable agents, and expanding the collected CD8+ T cells.

The present invention relates to a method for selecting a cell or a virus expressing on its surface an antigen-binding protein specifically binding to a protein antigen of interest (PAI) while counter selection using a similar protein antigen (SPA) is applied. Further, the invention provides a method for determining the sequence of a nucleic acid encoding an antigen-binding protein or an antigen-binding part thereof and a method for producing a cell expressing a nucleic acid encoding an antigen-binding protein or an antigen-binding part thereof. The invention also relates to a method for treating a subject with a selected cell population.

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.

A method of screening an antibody comprises preparing a serum having a target antibody and a non-target antibody; providing the serum with a first antigen that specifically binds the target antibody to obtain a first mixture; selectively obtaining the first conjugate by separating the first conjugate from the non-target antibody in the first mixture; dissociating the first conjugate, and a redundant non-target antibody adsorbed to the first conjugate into the first antigen, the target antibody and the redundant non-target antibody; removing the first antigen to obtain a second mixture of the target antibody and the redundant non-target antibody; providing the second mixture with a second antigen to form a second conjugate, so that third mixture including the target antibody and the second conjugate may be obtained; and selectively obtaining a target antibody by separating the second conjugate from the target antibody in the third mixture.

Cells and lipid-based structures are described herein, in particular cells and lipid-based structures comprising membrane portions derived from cells having a label covalently attached thereto, as are compositions and kits comprising such cells and structures, and methods for using the cells and structures, in particular for determining membrane coverage and/or orientation as well as for screening methods/assays, and the like.

The invention relates to methods and devices for quantitative determination of bacteria.

Disclosed is a method for preparing nanoscale electrodes comprised of electrochemically grown noble metal nanowires, and use of the same for the detection of extremely small concentrations of molecules. Such nanoscale electrodes provide target molecule release information from submicron areas on the cell surface, significantly increasing the spatial resolution of the target molecule mapping of a cell surface to enable localization of target molecules on the cell surface, which can be critical for the detection of certain cells with different properties in a given group of cells, such as circulating tumor cells.
