The present invention relates to procedures for the detection or for the determination of solid phase-associated factors, which are multiply associated with the same solid phase. According to the invention, the sample is brought into contact with a transmitter particle, on which at least one ligand having binding affinity for a solid phase-associated factor and a transmitter are immobilized, and a receiver particle, on which at least one ligand having binding affinity for said solid phase-associated factor and a receiver is immobilized, and then the signal is determined which results when transmitter and receiver are brought sufficiently close to one another. In particular, the invention relates to the detection of cell surface receptors which can be used for the typing of cells or for the determination of cell activation states. It is thus possible to replace the hitherto widely customary flow cytometry by a more simple procedure.

Detection and determination of solid phase-associated factors

The invention relates to monoclonal antibodies and fragments thereof which are specific for Mycoplasma pneumoniae P2 protein and have a cross-reactivity of 1% or less with five other species of the genus Mycoplasma and other pathogen species of the concomitant flora, and to methods for the preparation of the monoclonal antibodies according to the invention. The invention furthermore relates to hybridomas which produce the antibodies according to the invention, and to methods for the preparation thereof. Finally, the invention relates to the use of the monoclonal antibodies according to the invention for detecting Mycoplasma pneumoniae in a sample.

Monoclonal antibodies against Mycoplasma pneumoniae, hybridomas

Amine oxide-containing agents for immunochemical assays are described. The amine oxides are contained in constituents of agents for such assays which are used for receiving samples. The amine oxides are also contained in those constituents of the agent in which the immunochemical reaction takes place. The amine oxides bring about an improvement of the assay result, i.e., they increase the sensitivity of the detection and of the determination of an analyte contained in biological material.
