Protein Phosphorylation By Melissa George
eBook (PDF): $8.99
Phosphorylation is an important covalent post-translational modification (PTM) in cell signaling pathways. This modification is a reversible process, and is catalyzed by protein kinases. Study showed... More > that over 30% of eukaryotic proteins are subject to phosphorylation. Phosphorylation modification has mainly two regulatory mechanisms for the target proteins: (1) phosphorylation may cause a conformational change in the structure of modified proteins, such as enzymes and receptors, turning “on” or “off” the function. (2) phosphorylation changes the proteins’ affinity to their effector, by doing so, phosphorylated proteins can recruit or release their downstream effectors. Hence, it is conceivable that phosphorylation modification regulates a broad range of biological activities, such as cell growth, cell metabolism, cell division, and so on.< Less
Lipid Profiling By Melissa George
eBook (PDF): $8.99
Neutral lipids are the triglycerides which consist of three fatty acids attached to a glycerol molecule. Cholesterol is also a neutral lipid. Neutral lipids such as cholesterol esters and... More > triglycerides are insoluble in water and essentially lack detergent properties. Phospholipids are a class of lipids that are a major component of all cell membranes. Phospholipids belong to the lipid family of biological polymers. A phospholipid is composed of two fatty acids, a glycerol unit, a phosphate group and a polar molecule. There are no simple methods available for analysis of phospholipids since the close range of polarity between different phospholipid species makes detection difficult.< Less
Mass Spectrometry for Protein Identification By Melissa George
eBook (PDF): $8.99
The starting point is a given protein sample that may be a single protein or a complex mixture of different proteins. An enzyme, often trypsin, is used to digest the proteins to peptides. In most... More > cases, one or more stages of chromatography are applied to regulate the flow of peptides into the mass spectrometer. Peptides are then selected for one at a time in the first stage of mass analysis. Each isolated peptide is induced to fragment by collision in the second stage of mass analysis. The fragments are captured to synthesize a MS/MS spectrum.< Less

Human Cardiac Fibroblasts By Melissa George
eBook (PDF): $8.99
HCF from Creative Bioarray Research Laboratories are isolated from the human heart. HCF-a are cryopreserved at secondary culture and delivered frozen. Each vial contains >5 x 10^5 cells in 1 ml... More > volume. HCF-a are characterized by immunofluorescent method with antibody to fibronectin. HCF-a are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi. HCF-a are guaranteed to further expand for 15 population doublings at the condition provided by Creative Bioarray.< Less
Custom Aqua Peptides By Melissa George
eBook (PDF): $8.99
The targeted proteins in the complicated biological samples would release free peptide fragments induced by specific enzymatic cleavage, and the stable peptides with unique primary sequences in the... More > digest mixture would be utilized as surrogates for corresponding parent proteins, so the small-molecular peptides can be quantified to estimate the protein concentration.< Less

More > help you with a diversity of vitamin content analysis in whatever you can image, breakfast cereal, fruit juice, soft drinks, infant formula, nutritional supplements and much more products, with the analytical and technical combination of LC/MS/MS, UHPLC–HRAM–MS/MS, HPLC with UV or FLD detection, GC-MS and more solutions.< Less
Isotope Labeled Aqua Internal Standard Peptide By Melissa George
eBook (PDF): $8.99
While isotope methods establish only relative quantification of expressed proteins, the absolute quantification (AQUA) strategy can provide information for the precise determination of protein... More > expression and post-translational modification levels. The AQUA method relies on the use of a synthetic internal standard peptide that is introduced at a known concentration to cell lysates during digestion. Analysis of the proteolyzed sample by a selected reaction monitoring (SRM) experiment in a tandem mass spectrometer results in the direct detection and quantification of both the native peptide and isotope labeled AQUA internal standard peptide.< Less
