Label-free analysis is a powerful technique for identifying and quantifying relative changes in complex protein samples. In this method, samples are run individually and identified by MS/MS information. Relative quantitation of different samples is then analyzed by aligning chromatographic peak areas of precursor ions between various runs. The most distinctive advantage is that it quantifies proteins without any use of labels, and can analyze unlimited number of samples. Since Label-free is relatively simple and easy compared to other proteomics techniques, it has been widely used for proteomics study and biomarker discovery.
MtoZ Biolabs is proud to offer Label-Free Quantitative Proteomics Service with faster simpler results. We can also perform MS3 analysis to ensure higher analytical accuracy of qualification and quantitation.
Service Advantages
1. Does not require expensive isotope labeling reagents, resulting in a shorter experimental duration.
2. Enables comparative analysis of differential protein expression across different species.
3. Overcomes sample number limitations inherent to labeled quantification techniques, offering greater flexibility and convenience.
