This invention describes a novel method for identification of known and unknown viruses from various biological and non biological samples using carrier suitable for immobilisation of membrane proteins of different target cells of human, animal or bacterial origin for capturing the virus, whose peptides are identified by mass spectrometry analysis, a diagnostic kit based on the said method and the use thereof.

Methods are disclosed to detect, characterize, measure, and quantify human and humanized antibodies, and their conjugates, that may be present in pre-clinical animal biological samples, or human biological samples, including plasma/serum and tissue samples.

Disclosed are a mixture comprising at least one internal standard protein, a container comprising the mixture, a method for preparing a container with the mixture, a method for determining the amount of a target protein present in a sample, providing a container comprising the mixture, as well as a kit for carrying out the methods.

The present application relates to compositions and methods for diagnosing patients with a history of early-life adversity (ELA), and for preventing, treating, or reducing psychological distress in patients with a history of ELA.

The present disclosure relates to a composition for detecting or measuring an analyte and an analysis method using the composition. In particular, efficiency and performance of sample analysis may be greatly improved through the composition and analysis method of the present disclosure.

Methods for detecting lung cancer cells, or lung cancer subtypes, by measuring levels of metabolites are provided. Methods of treating identified cancers are likewise provided

Methods of determining the stoichiometry of a viral capsid and/or determining the heterogeneity of protein components in a viral capsid are disclosed.

The present invention provides assays and assay systems for use in spatially encoded biological assays. The invention provides an assay system comprising an assay capable of high levels of multiplexing where reagents are provided to a biological sample in defined spatial patterns; instrumentation capable of controlled delivery of reagents according to the spatial patterns; and a decoding scheme providing a readout that is digital in nature.

A microorganism identification method utilizing mass spectrometry is provided. More specifically, a method for identifying a phylotype of Cutibacterium acnes utilizing mass spectrometry is provided. The method includes a) a step for reading out a m/z value of a peak derived from a marker protein on a mass spectrum which is obtained by mass spectrometry of a sample containing microorganisms; and b) a step for judging whether the sample contains Cutibacterium acnes (C. acnes) based on the m/z value.

Methods are described for measuring the amount of C peptide in a sample. More specifically, mass spectrometric methods are described for detecting and quantifying C peptide in a sample utilizing on-line extraction methods coupled with tandem mass spectrometric or high resolution/high accuracy mass spectrometric techniques.
