Tissue Proteomics Service
Tissue proteomics uses LC-MS/MS to identify and compare proteins in whole-tissue samples. The resulting protein profiles support research into tissue biology, disease-associated changes, and responses to experimental treatments.
MtoZ Biolabs analyzes animal and plant tissues, including fresh, frozen, FFPE, and selected difficult or low-input materials. Sample conditions, research objectives, and expected results guide the choice of analysis.
- Protein identification and relative quantification
- Comparative tissue analysis with appropriate study design
- Fresh, frozen, FFPE, and specialized tissue assessment

What Is Tissue Proteomics?
- Tissues are organized collections of cells and extracellular components that perform specific biological functions. Liver, brain, muscle, tumor, and plant tissues differ in cellular composition, structural proteins, and matrix characteristics. These differences shape the proteins present in a sample and can also influence protein extraction and the interpretation of tissue-level changes.
- Tissue proteomics analyzes proteins extracted from tissue using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Following tissue disruption, protein extraction, and enzymatic digestion, LC-MS/MS supports protein identification and relative abundance profiling. With suitable controls and biological replicates, researchers can compare protein abundance across tissue conditions, disease models, or experimental treatments.

Sample Submission Requirements
Review recommended tissue amounts, accepted sample formats, and key submission requirements.
| Sample type | Recommended input | Submission notes |
|---|---|---|
| Routine animal soft tissue | 20–50 mg recommended | Fresh or snap-frozen samples; remove blood and non-target tissue where appropriate. |
| Plant tissue | 2–5 g ground powder recommended | Provide the species and tissue type; matrix characteristics may affect preparation. |
| Frozen tissue | Minimum input varies by tissue type. | Snap-freeze in liquid nitrogen, store at −80°C, and ship on dry ice. |
| FFPE block, section, or scroll | Depends on project | FFPE blocks, sections, or scrolls can be submitted at room temperature. Protein extraction is required. Fixation and paraffin embedding services are not provided. |
| Tissue lysate or protein extract | At least 50 μg protein per sample, quantified by BCA or Bradford assay. | Provide the extraction or lysis buffer composition and the original tissue source. |
| Biopsy or LCM-derived material | Depends on project | Provide available amount, material format, and intended analysis for feasibility review. |

Applications of Tissue Proteomics
Tissue proteomics supports research into environmental responses, tissue development, plant biology, and tissue regeneration.
Result Considerations
Tissue proteomics results should be reviewed in the context of sample comparability and biological variation.
Relative abundance
Routine intensity-based quantitative results describe relative changes rather than absolute protein concentrations.
Bulk tissue composition
Protein profiles may reflect differences in cell proportions or extracellular matrix; not directly resolve cell-specific or spatial expression.
Differential protein evidence
Protein changes should be evaluated with study design, within-group variation, and statistical evidence. Association alone does not establish causality.
