We have developed innovative solutions for optimizing the process of accurately quantifying proteins in complex biological matrices and other complex mixtures.
Label-Free DIA Quantitative Proteomics
Data-Independent Acquisition (DIA) is a label-free quantitative technique which provides highly consistent quantitation and broad proteome coverage1. We create a customized spectral library with your specific sample and then analyze individual samples using nano-flow LC-MS/MS with DIA scanning and quantitation2.
Label-Free DIA Quantitative Proteomics service is ideal for long-term projects or projects with large sample sets which require accurate and reproducible quantitation.
