The present invention relates to the fields of immunology and biochemistry. Particularly, the present invention describes methods, devices and kits for early detection of clinical conditions having associated changes in systemic angiogenic activity, particularly cancers, inflammatory conditions, infections, and events associated with pregnancy and abortion.

Platelet biomarkers for cancer

The invention provides a probe and a method of making the probe that is removably insertable into a gas phase ion spectrometer, the probe comprising a substrate having a surface and a hydrogel material on the surface, the hydrogel material comprising binding functionalities for binding with an analyte detectable by the gas phase ion spectrometer. The invention also provides a probe and a method of making the probe that is removably insertable into a gas phase ion spectrometer, the probe comprising a substrate having a surface and a plurality of particles that are uniform in diameter on the surface, the particles comprising binding functionalities for binding with an analyte detectable by the gas phase ion spectrometer. Further, the invention provides a system comprising the probe of the present invention and a gas phase ion spectrometer comprising an energy source that directs light to the probe surface to desorb an analyte and a detector in communication with the probe surface that detects the desorbed analyte. The invention also provides a method for desorbing an analyte from a probe surface, the method comprising exposing the binding functionalities to a sample containing an analyte under conditions to allow binding between the analyte and the binding functionalities, and desorbing the analyte from the probe by gas phase ion spectrometry.

Probes for a gas phase ion spectrometer

This invention provides methods and materials for mapping interaction characteristics between components of a multicomponent biological complex. The methods involve capturing a multicomponent complex on a solid support and washing the support with a series of elution washes forming a gradient of solute concentrations, and determining whether a particular elution wash eluted a particular component.

Protein interaction difference mapping

The present invention relates to methods for correlating gene and protein expression in a cell.

Method for correlating gene expression profiles with protein expression profiles

A method that analyzes mass spectra using a digital computer is disclosed. The method includes entering into a digital computer a data set obtained from mass spectra from a plurality of samples. Each sample is, or is to be assigned to a class within a class set having two or more classes and each class is characterized by a different biological status. A classification model is then formed. The classification model discriminates between the classes in the class set.

Method for analyzing mass spectra

A method for processing time-dependent signal data is disclosed. The time-dependent signal data are received in a memory, wherein the time-dependent signal data represent a time-dependent signal, and wherein the time-dependent signal data include representations of time-of-flight values of ions, or values derived from time-of-flight values of ions. The time-dependent signal data are scaled with a time-dependent scaling function.
