MtoZ Biolabs provides specialized Plant Single-Cell Proteomics Service to enable protein-level analysis at single-cell resolution in plant systems. By integrating controlled single-cell preparation with high-sensitivity mass spectrometry, this service supports qualitative and quantitative characterization of proteins from individual plant cells, enabling cell-type-resolved investigation of complex plant tissues.
What Is Plant Single-Cell Proteomics?
Plant tissues are composed of diverse cell types that differ in developmental state, metabolic activity, and regulatory programs. Bulk proteomics averages protein signals across mixed populations, which can obscure cell-specific regulatory features. Plant single-cell proteomics directly measures protein expression within individual cells, providing functional insight that complements transcript-based single-cell approaches.
Because proteins represent the functional output of gene regulation, single-cell proteomics is particularly valuable for studying plant development, differentiation, and stress responses, where post-transcriptional regulation and protein-level control play critical roles.
Plant Single-Cell Proteomics Service at MtoZ Biolabs
MtoZ Biolabs provides a structured Plant Single-Cell Proteomics Service covering single-cell isolation, low-input proteomics processing, and quantitative mass spectrometry analysis. The service supports protein profiling at the level of individual plant cells or defined small cell populations.
1. Single-Cell Isolation and Selection
Plant single cells or nuclei are obtained using tissue-adapted dissociation strategies. Cell isolation can be performed by fluorescence-activated cell sorting (FACS) or microfluidic-based platforms, enabling either unbiased single-cell collection or targeted selection of specific cell types.
2. Low-Input Proteomics Sample Preparation
Protein extraction and enzymatic digestion workflows are designed for single cells or limited cell numbers. These procedures ensure reproducible peptide generation while remaining compatible with plant-derived samples containing polysaccharides and secondary metabolites.
3. Quantitative Proteomics Approaches
Quantitative analysis can be performed using multiplexed labeling strategies such as Tandem Mass Tag (TMT) labeling, or label-free quantification methods. The selection of the quantitative strategy is based on experimental design, sample throughput requirements, and comparison objectives.
4. LC-MS/MS-Based Proteomic Analysis
Peptide samples are analyzed using LC-MS/MS-based proteomics workflows to enable protein identification and quantitative comparison across individual cells, cell populations, or experimental conditions.

FAQ
Q1: What types of samples are suitable?
This service is suitable for isolated single plant cells or high-quality single-cell suspensions derived from tissues such as roots, leaves, vascular tissues, or meristems.
Q2: How should I prepare my samples?
Single-cell samples should be prepared to preserve protein integrity, kept under cold conditions, and free of debris or excessive contaminants. Avoid harsh treatments and repeated freeze-thaw cycles.
