For the analysis of protein-protein interactions and protein conformations, cross-linking coupled with mass spectrometry (CXMS) has become an essential tool in recent years. A variety of cross-linking...
"Native" mass spectrometry has become a valuable tool for structural biology. In this issue of Chemistry & Biology, Quintyn et al. (2015) show that modified instruments capable of surface-induced dis...
Contemporary structural biology research promises more than just static snap-shots of molecular machineries. This goal is not just facilitated by combining different structural biology techniques, but...
Protein interaction surface mapping using MS is widely applied but comparatively resource intensive. Here a workflow adaptation for use of isotope coded tandem mass tags for the purpose is reported. T...
Rather than functioning independently, proteins tend to work in concert with each other and with other macromolecules to form macromolecular complexes. Affinity purification coupled to mass spectromet...
RATIONALE: Studying tissue samples from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. ...
The purpose of this study is to evaluate the basis for the reported good effects of antioxidant supplementation. A blood test using Mass Spectrometry will measure DNA damage which is expec...
We are collecting brain tissue specimens and blood samples from patients at Vanderbilt University Medical Center who are undergoing intracranial surgery to remove brain tissue, including b...
RATIONALE: Erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving erlotinib before surgery may make the tumor smaller and reduce the am...
RATIONALE: Studying samples of tumor tissue and blood in the laboratory from patients with cancer may help doctors learn more about changes that occur in RNA and identify protein expressio...
A mass spectrometry technique using two (MS/MS) or more mass analyzers. With two in tandem, the precursor ions are mass-selected by a first mass analyzer, and focused into a collision region where they are then fragmented into product ions which are then characterized by a second mass analyzer. A variety of techniques are used to separate the compounds, ionize them, and introduce them to the first mass analyzer. For example, for in GC-MS/MS, GAS CHROMATOGRAPHY-MASS SPECTROMETRY is involved in separating relatively small compounds by GAS CHROMATOGRAPHY prior to injecting them into an ionization chamber for the mass selection.
A microanalytical technique combining mass spectrometry and gas chromatography for the qualitative as well as quantitative determinations of compounds.
Methods for determining interaction between proteins.
An analytical method used in determining the identity of a chemical based on its mass using mass analyzers/mass spectrometers.
Analysis of PEPTIDES that are generated from the digestion or fragmentation of a protein or mixture of PROTEINS, by ELECTROPHORESIS; CHROMATOGRAPHY; or MASS SPECTROMETRY. The resulting peptide fingerprints are analyzed for a variety of purposes including the identification of the proteins in a sample, GENETIC POLYMORPHISMS, patterns of gene expression, and patterns diagnostic for diseases.
