摘要:
The present invention provides a device capable of simply formulating an arbitrary gradient pattern in a low flow gradient high performance liquid chromatography. That is, the present invention provides a split tubing apparatus for a gradient high performance liquid chromatography, which comprises a solvent inlet part, a split tubing part split into two or more plural tubes, and a solvent outlet part.
摘要:
A inner-wall-coated capillary in which a zwitterionic polymer including a phosphate group including, for example, a phosphorylcholine group, is fixed on a wall surface including, for example, silanol by ionic interaction, is obtained by flowing a polymer solution including a phospholipid polymer combining, for example, MPC and BMA or MPC and SMA, through a capillary that includes silanol on the wall surface, for example. Consequently, adsorption of phosphorylated compounds can be prevented simply and highly durably.

The present inventor has established protein abundance index (PAI, π) to determine the protein contents in a protein mixture solution using nanoLC-MSMS data. Digested peptides were analyzed by nanoLC-MS/MS and the obtained results were applied to a Mascot protein identification algorism based on tandem mass spectra. For absolute quantitation, PAI was converted to exponentially modified PAI (EMPAI, m π), which is proportional to protein contents in the protein mixture. EMPAI was successfully applied to comprehensive protein expression analysis and performed a comparison study between gene and protein expression in an HCT116 human cancer cells. Accordingly, the present invention provides a method and a computer program for quantifying the protein contents based on the protein abundance index.

Problem: An object of the present invention is to quantitate with good accuracy, furthermore, quantitate absolutely, one or a plurality of biological molecules in a sample such as a tissue, a biological fluid, a cell, a cell organ or protein complex. Solution: By adding a metabolically isotope labeled biological molecule as an internal standard substance and measuring with a mass spectrometer, quantitating with good accuracy one or a plurality of target molecules in a sample has become possible. In addition, by performing waveform separation processing during mass analysis, a highly accurate quantitative analysis method of mass analysis is provided.
摘要:
The present invention provides a packing for chromatography. Specifically, it provides a packing for chromatography in which a hydrophilic polymeric material is bound to the surface of a porous carrier, and a carbon chain is chemically bound inside the pore. By the use of the packing according to the present invention for analysis of low molecular weight compounds in a biological sample, a pretreatment such as removal of proteins etc. becomes unnecessary, and the biological sample can be directly analyzed.
摘要:
It is to provide a capillary having adsorbed a polymer. A capillary having absorbed on an inner wall of the capillary, an ionic polymer having positive electric charge and an ionic polymer having negative electric charge alternately, and a process for producing the same.
