摘要:
A device is described for pre-concentration and purification of analytes from biological samples (such as human serum, plasma, homogenized solid tissue, etc.) to be analyzed by Matrix-Assisted Laser Desorption Ionization Mass Spectrometry (MALDI MS) and methods of use thereof are provided.
摘要:
The present invention includes a cleavable surfactant/detergent compound of the following formula: wherein the variables are defined herein. Embodiments of the cleavable surfactant/detergent compound are useful, for example, in methods for isolating a hydrophobic molecule that include providing a plasma comprising a hydrophobic molecule, applying the cleavable surfactant to the plasma so that the surfactant engages the hydrophobic molecule, cleaving the surfactant from the hydrophobic molecule, and analyzing said hydrophobic molecule.
摘要:
A method of modifying protein samples that comprises combining the sample with a peroxycarbonate solution and inserting the sample into a mass spectrometer. The present invention also includes methods of N-terminus characterization.
摘要:
Cleavable compositions that comprise a polar head, cleavable linker, and a hydrophobic tail; and methods for using them to isolate hydrophobic molecules.
摘要:
The present invention provides methods for obtaining information of a plurality of target molecules by matrix free LDI MS. Mass tagged complexes for detection of target molecules comprise a target molecule binding domain, and a mass tag separated by a cleavable linker. Methods of the invention may be used for example to analyze the distribution of a multiple target molecules in a complex sample, such as a tissue section.
