Described herein are methods such as multi-omic methods for assessing a disease such as cancer. The multi-omic methods may integrate proteomic, transcriptomic, genomic, lipidomic, or metabolomic data. The method screening diseases or disease states. Also described herein are methods for screening for diseases or disease states from biological samples. The methods may include assessing whether a nodule, mass, or cyst is cancerous.

Methods and devices to capture and analyze aerosolized particles such as protein biomarkers and their truncated proteoforms characteristic of a disease, including a respiratory disease, in exhaled breath to enable rapid detection of diseases are disclosed. The disclosed methods and systems selectively capture aerosolized particles using a packed bed column. The captured particles are then eluted using one or more solvents and analyzed using devices including mass spectrometry.

Systems and methods for automated sample preparation and processing of protein corona are described herein, as well as its application in the discovery of advanced diagnostic tools as well as therapeutic agents.

The present invention relates to a method for quantitative measurement of catechol estrogen bound protein in blood sample. By detecting adduction levels of binding sites of the catechol estrogen on the protein in blood sample, the catechol estrogen bound protein in the blood sample can be detected quantitatively and a limit of quantitation can be decreased.

Compositions and methods for predicting due date and time to birth for a pregnancy with significantly higher accuracy than current clinical methods. The compositions and methods for predicting due date and time to birth for a pregnancy can also identify those pregnancies that will deliver earlier than the due date derived from Last Menstrual Period (LMP) and/or obstetric ultrasonography (US) dating.

The invention relates to a method to evaluate mass spectrometry data for the analysis of peptides from biological samples, particularly MALDI-TOF mass spectrometry data, comprising the steps of: providing expected mass defects; determining measured mass defects, i.e. the mass defects resulting from the mass spectrometry data; and comparing the measured mass defects with the expected mass defects.

The invention relates to the diagnosis of a condition characterised by TDP-43 proteinopathy by mass spectrometry using one or more signature peptides of TDP-43 species.

The present invention relates to compounds which are suitable to be used in mass spectrometry as well as methods of mass spectrometric determination of analyte molecules using said compounds.

There is disclosed a method of identifying colon cancer-specific vesicle-associated proteins from a tissue sample of a subject. The method comprises isolating tissue-resident extracellular vesicles from the tissue sample; identifying vesicle-associated proteins associated with the isolated tissue-resident extracellular vesicles; quantifying the identified vesicle-associated proteins to identify one or more major vesicle-associated proteins; creating vesicle-associated protein profiles for the identified vesicle-associated proteins; and comparing the vesicle-associated protein profiles for the identified vesicle-associated proteins with pre-determined vesicle-associated protein profiles of the tumour tissue samples and/or non-tumour tissue samples.

Disclosed herein are compositions and methods for assaying for low volumes of proteins and/or nucleic acids, optionally in parallel.
