Abstract: Methods for diagnosis of HPV infection in a subject are provided. HPV infection in a subject can be determined by generating mass profile data for a biological sample from the subject and correlating the mass profile data with reference mass profiles to detect the presence or absence, and/or quantity of at least one biomarker associated with HPV infection. Methods for detecting at least one biomarker associated with HPV infection in a biological sample are also provided.

Abstract: The present invention pertains to methods of quantifying the levels of at least one analyte in a sample or extract comprising adding a known quantity of at least one internal standard to the sample or extract. The present invention also relates to internal standards used in mass spectrometry, as well as compositions thereof. Internal standards for mass spectrometry according to the invention can be used, for example, to assist aligning mass spectra obtained from two different samples, each of which comprises the internal standard. In one aspect of the invention, the internal standard is a dendrimer. A labile internal standard may be used in conjunction with the dendrimer.

Abstract: Mass spectrometry techniques for determining the status of sepsis in an individual are provided. A biomarker profile resolved from a biological sample, taken from the individual, using a mass spectrometry technique is compared to a reference biomarker profile. A single such comparison classifies the individual as belonging to or not belonging to a reference population. The individual's biomarker profile and the reference biomarker profile comprise a plurality of ions each having a mass-to-charge ratio of about 100 Daltons to about 1000 Daltons. The plurality of ions can be detected by electrospray ionization mass spectrometry in positive mode. The comparison uses a decision rule, such as a classification tree, that determines the status of sepsis in the individual without requiring knowledge of the identity of the biomarkers in the biomarker profile from the individual and without requiring knowledge of the identity of the biomarkers in the reference biomarker profile.

Abstract: Methods for isolating a compound from a multipart, typically biological sample. The methods use at least one paramagnetic particle having an associated electronic charge to bind compounds with the opposite charge to form a particle/compound complex. Alternatively, the paramagnetic particles have a ligand or functional group with an affinity for a target compound to form a particle/compound complex. The complex can be immobilized by applying a magnetic field to the particle/protein complex. The sample may be further processed to obtain a protein sample in a more pure form or a sample depleted of select compounds.
