DESCRIPTION
The Quantitative Peptide Retention Standard is a quantitative standard that is useful during the calibration, development, and troubleshooting of chromatographic separations ensuring confidence in results. This standard is rigorously QC tested for purity and quantitative formulation and is specifically designed with the following features: • Peak Retention for chromatographic reproducibility • UV absorptivity for signal reproducibility • Low to high mass range for MS • Water solubility • Tryptic-like peptides for peptide mapping studies
