Synpeptide Co Ltd HeavyPeptide AQUA Custom Synthesis Service provides isotopically labelled, AQUA-grade peptides for the relative and absolute quantitation of proteins at very low concentrations in complex protein mixtures. Peptides are synthesized using the latest Fmoc solid-phase technology and purified by HPLC. All HeavyPeptide sequences come with mass spectrometric analysis, and AQUA Ultimate and QuantPro-grade peptides also come with analytical HPLC data. Additionally, we offer a wide range of labels, modifications, scales, and purities.

· Quality—synthesized using pure materials and packaged using ArgonGuard

· Accuracy—concentration precision for reproducible results

· Sensitivity—provides for the absolute quantification of low-abundance proteins

· Specificity—Up to 100% peptide sequence specificity

· Flexibility—extensive list of available modifications, solvents, concentrations, and formats
