In order to study the differential protein expression in complex biological samples, strategies for rapid, highly reproducible and accurate quantification are necessary. Isotope labeling and fluorescent labeling techniques have been widely used in quantitative proteomics research. However, researchers are increasingly turning to label-free shotgun proteomics techniques for faster, cleaner, and simpler results. Mass spectrometry-based label-free quantitative proteomics falls into two general categories. In the first are the measurements of changes in chromatographic ion intensity such as peptide peak areas or peak heights. The second is based on the spectral counting of identified proteins.
Abvigen Label Free Technology Service application is oriented to disease marker screening, drug action target research, special function protein screening, pathogenesis and regulation mechanism research, action mechanism research, and plant stress resistance research.
No isotope labelling required
Near the original state
Not subject to sample conditions
Make at least three technical or biological repetitions
After the two parties communicate and agree, determine the experimental plan, determine the service requirements - sign the contract - advance payment - start the experiment - deliver the results
