Improving the specificity and selectivity of your assay Your LC-MS assay is only as good as its power to discern your target compound from everything else. Standards dissolved in clean solvents can make beautiful assays, but analytes in real-world samples can behave...

Guide decisions during cell line development with more information at the intact level
Monitoring product quality attributes (PQAs) throughout monoclonal antibody (mAb) development is vital to ensuring drug safety and efficacy. By adopting orthogonal analytical techniques and integrating new technologies that have the potential to provide more information, it is possible to improve product quality and manufacturing efficiency and make more informed decisions.

How do I set up my processing method to calculate the RRT of the main peak to 10kD in karat 32 software?
Current proteomics software compatibility for ZenoTOF 7600 system
Below is a summary of various other software packages that are useful for processing proteomics data from the ZenoTOF 7600 system. Note this list is not comprehensive and only covers the tools we have lightly tested to date. Acquisition Type Software Files needed...
Excel macro for plate building for transformation of 96-well to 384-well plates with generation of batch lists for SCIEX OS software
This macro-enabled workbook is designed to help with creating a formatted analysis list for the Echo® MS system, using 96-well plate maps or lists
sMRM Pro Builder template tutorial
The sMRM Pro Builder template is an Excel-based tool that can help you implement large panels of analytes in your lab. The Excel sheet will take your preliminary experimental results and compute retention times, retention time window widths and dwell time weighting to optimize your targeted assay.
MRM method transfer from a SCIEX Triple Quad or QTRAP 6500+ system to the SCIEX 7500 system
General recommendations when beginning method development Objective: The purpose of this document is to provide a quick reference for transferring MRM-based quantification methods from a SCIEX Triple Quad or QTRAP 6500+ system to a SCIEX 7500 system. While the best...
What is the difference between MRM3 vs MS/MS/MS (MS3)?
The MRM3 workflow and the MS3 scan are functionally the same QTRAP system scan, but used with different goals in mind. The main difference is how these scans are used in the whole MS workflow. With MS3 scans, you can use these in a data dependent mode for discovery...
How do I define the experimental design (the metadata) for my SWATH acquisition study within the OneOmics suite? What are the requirement for replicates?
In quantitative Omics research, the goal is to understand which analytes (protein or metabolite) are perturbed between experimental conditions; therefore we carefully design our studies to explore these questions. The algorithms used within the Assembler application...
Quickly compare identification results from ProteinPilot software
When a ProteinPilot Software search is complete, a ProteinPilot report is generated that contains all the false discovery rate (FDR) analysis information. More information on using the large and small ProteinPilot reports can be found here When doing method...
Breaking down the SCIEX Triple Quad™ 7500 LC-MS/MS System – QTRAP® Ready
Sensitivity and robustness carry different meanings in the world of mass spectrometry. Generally, sensitivity refers to an instrument’s ability to achieve lower limits of detection (LOD). Robustness, on the other hand, refers to an instrument’s ability to consistently...
