Analyze multiple samples simultaneously A global internal standard for peptide quantitation itraq reagents: the industry standard cited in over 84 peer-reviewed papers The ability to simultaneously analyze multiple samples readily enables important research into dosing, temporal investigations, biomarker elucidation, and absolute quantitation of target proteins. itraq reagents are a multiplexed set of four or eight isobaric By combining itraq reagents with AB SCIEX instrumentation and application-specific software such as ProteinPilot software you ll achieve the meaningful, highly accurate results for confident quantitative protein expression analysis. Peptide quantitation mtraq reagents To get quantitation results you can trust it is always better to use an internal standard. But synthesizing internal standards can take up to 6 weeks, and not all of them will be appropriate for MRM analysis. The mass differential mtraq Reagents are specifically designed for peptide quantitation using MRM and are significantly more economical when larger numbers of peptides need to be monitored. (same mass), amine-specific tags that yield labeled peptides that are easily quantitated using mass spectrometry. Achieve identification and quantitation of multiple samples simultaneously Available as duplex and triplex to radically increase sample throughput The simple peptide-based itraq workflow eliminates many of the restrictions and difficulties presented by other strategies, allowing protein coverage that includes post-translational modifications, affinity pull-downs, and membrane proteins.

ichemistry solutions for clinical research applications Easy compound derivatization for up to 1x boost in intensity ichemistry solutions for amino acid analysis Faster performance. Better accuracy. Pushing the limits in sensitivity Mass spec is a great tool for compound detection and quantitation, but sensitivity can sometimes be negatively impacted by matrix suppression, high background noise levels, poor ionization efficiency, or poor compound fragmentation. Amplifex Reagents are the only derivatizing agents intelligently designed, synthesized, and tested to boost ionization efficiency and improve fragmentation and chromatographic properties. Amplifex Reagents take the complexity out of compound derivatization with a simple (one-step), fast (3 minute, reproducible, and robust) derivatization procedure. Just mix the sample, incubate, and you re ready for analysis. Amplifex reagents are mass tags designed to react universally with a specific functional group. For example: Amplifex -Diene Reagent can be used to derivatize any molecule with a cis-diene system, including compounds such as Vitamin D3 and Vitamin D2 analogs, among others. The result is a signal enhancement of up to 1-fold. Amplifex -Keto Reagent is universal and reacts with keto or aldehyde compounds, including ketosteroids such as Testosterone, among others. Signal enhancements improve mass limits of detection by up to 5-fold. Derivatization is no longer a painful day-long process. The most diverse of the ichemistry solutions, atraq reagent is the ideal solution to quantitate amino acids in samples ranging from protein hydrolysates for omics applications, food and consumer products, and physiological fluids for clinical research and forensic toxicology samples. atraq reagents save time and money with faster, more complete analysis. With atraq, you can quantitate up to 45 amino acids and amines from a wide variety of samples, including physiological fluids, protein hydrolysates, food and beverages, and culture media more than 3 times faster than conventional amino acid analyzers. Get confident identification, superior accuracy, and precision with internal standards for every amino acid Achieve higher throughput with an analysis time of 18 minutes per sample Add custom amines, amino acids and small peptides, and create corresponding internal standards Amplifex Diene Signal Enhancement Amplifex Keto Signal Enhancement 1,25-Dihydroxyvitamin D3 2.3e5 2.2e5 2.e5 1.8e5 1.6e5 1.4e5 1.2e5 1.e5 8.e4 x165 4 pg DHVD3 1.6e4 1.e4 9. 8. 7. 6. 5. 4. 4-Cholesten-3-one 1 pg 4-Cholesten-3-one x58 Amino acid sample atraq 121 28 NHS 113 28 NH PSer 113 28 NH ASn MRM AA MW 113 AA MW 121 atraq - sample atraq - standard 6.e4 4.e4 2.e4 4 pg DHVD3...5 1. 1.5 2. 2.5 3. 3.5 4. 4.5 3. 2. 1.. 3 pg 4-Cholesten-3-one 3.5 4. 4.5 5. 5.5 6. 6.5 Internal standards 113 28 NH Ala 113 28 NH Pro... 113 28 NH Leu PSer ASn Pro Ala...
