MtoZ Biolabs provides the Label-Based Plant Proteomes Quantification Service by leveraging isotope labeling-based quantitative strategies to enable systematic and accurate comparison of plant protein abundance across different experimental conditions. This service enables researchers to achieve high quantitative accuracy and strong data comparability in plant proteomics studies. It is well-suited for parallel analysis of multiple sample groups and effectively reduces batch effects, providing reliable quantitative data to support research on plant growth and development, stress responses, and functional protein studies.

What Is Label-Based Quantitative Proteomics

The fundamental principle of label-based quantitative proteomics is to introduce chemical isotope or isobaric labels to distinguish peptides derived from different samples, enabling quantitative comparison of multiple samples within a single mass spectrometry analysis. Commonly used TMT and iTRAQ labels form stable covalent bonds with the N-terminus and lysine residues of peptides. Because these labels are designed to have identical total mass, identical peptides from different samples exhibit the same behavior during chromatographic separation and MS1 analysis. During subsequent fragmentation, the labels release reporter ions with distinct mass-to-charge ratios, and the intensities of these reporter ions reflect the relative abundance of the corresponding peptides and proteins, enabling reliable quantification.

Based on this principle, a typical label-based quantitative proteomics workflow includes protein extraction and quantification, enzymatic digestion under standardized conditions, sample-specific labeling, equal-ratio pooling, and LC-MS/MS analysis. Plant samples from different treatments or time points are combined into a single mixed sample after labeling to ensure that all samples are identified and quantified under identical analytical conditions. By comparing reporter ion signals, highly comparable protein quantification results can be obtained, making this approach suitable for multi-condition and complex plant proteomics studies.

Label-Based Plant Proteomes Quantification Service at MtoZ Biolabs

The Label-Based Plant Proteomes Quantification Service at MtoZ Biolabs is designed for diverse plant sample systems and integrates well-established isotope labeling strategies with robust and reliable mass spectrometry workflows to support multi-condition and multi-group quantitative comparisons. This service offers mainstream labeling approaches such as TMT and iTRAQ, with unified labeling and pooled analysis performed after protein digestion to reduce batch variability at the source. By analyzing multiple samples in parallel within a single LC-MS/MS run, reliable quantification of protein abundance changes across different treatments, time points, or tissue origins can be achieved.
