Thermo Scientific™ Pierce™ Peptide Retention Time Calibration Mixture, 50 µL
On demandThermo Scientific™ Pierce™ Peptide Retention Time Calibration Mixture, 50 µL
The Thermo Scientific Pierce Peptide Retention Time Calibration Mixture enables reversed phase liquid chromatography (LC) and mass spectrometry (LC-MS) users to optimize and confirm correct operation of their equipment.
The Pierce Peptide Retention Time Calibration Mixture is used to optimize and assess LC parameters, identify the total peptide elution window, and optimize MS parameters. Testing the mixture frequently throughout the lifetime of a column or including it in quantitative samples makes it possible to monitor and normalize LC-MS performance between samples and over time. When used with Thermo Scientific Pinpoint 1.1 software, the calibration mixture can predict peptide retention times based upon peptide sequence or relative retention time between instruments. The mixture can also be used with Pinpoint software to establish normalized collision energies between platforms. This allows normalization of methods and eases the transfer of quantitative methods between LC-MS platforms. Pinpoint software, sample files, tutorials, and videos can be downloaded from the Thermo Proteomics Portal.
