We describe an approach to screen large sets of MALDI-MS mass spectra for protein isoforms separated on two-dimensional electrophoresis gels. Mass spectra are matched against each other by utilizing extracted peak mass lists and hierarchical clustering. The output is presented as dendrograms in which protein isoforms cluster together. Clustering could be applied to mass spectra from different s...
Mushrooms are considered as important source of biologically active compounds which include low-molecular-mass protein/peptides (LMMP). In this study, we attempted to profile the LMMP from Lignosus rhinocerus, a wild medicinal mushroom, grown by static cultures (SC) and in stirred tank reactor (STR). Crude water extract (CWE) and protein fractions were profiled using H50 ProteinChip® arrays and...
Some nuclides emit multiple gamma rays or X-rays when they decay to the ground state. If these gamma rays and X-rays are emitted essentially at the same time, it is possible that multiple photons will be detected at the same time in the detector and appear as one full-energy peak in the spectrum. This is known as “Cascade” or “True Coincidence” summing. The most common example of this is Co, wh...
Reversed-phase chromatography was used to separate several forms of cholecystokinin-like peptides (CCKLP) from the pericardial organs (PCOs) of the spiny lobster Panulirus interruptus. Fast protein liquid chromatography of PCOs, stomatogastric ganglia (STGs) and eyestalks revealed five peaks of CCKLP (peaks A-E) that were common to all three tissues, as well as two additional peaks (peaks F and...
The peaks are not column bleed. Column bleed is a continuous stream of stationary phase degradation products eluting from the column. Column bleed is a component of the baseline and not a series of peaks. Column bleed increases with temperature, especially at temperatures near the column’s upper temperature limit. When temperature programming up to the upper temperature limit, a rise in the bas...
