MtoZ Biolabs provides advanced proteomics services to support animal research across discovery biology, mechanistic studies, and preclinical evaluation. Our Animal Research Proteomics Solutions help investigators profile protein expression, pathways, and post-translational modifications involved in reproductive development, disease mechanisms, nutritional metabolism, and toxicology evaluation in animal models.

Proteomics in Animal Research

Proteomics is the large scale study of proteins, their abundances, modifications, and interactions, and in animal research it is used to link molecular changes to physiological functions and observable phenotypes. By profiling protein networks across organs, tissues, and biofluids, proteomics helps reveal mechanisms underlying reproductive development, disease progression, immune responses, nutritional metabolism, and toxicology outcomes in animal models and production species. This systems level view allows researchers to move beyond single markers, identifying pathways and protein signatures that explain complex traits and guide intervention, breeding, health monitoring, and safety assessment in a scientifically robust way.

• Pathway and network analysis of hormones, receptors, and downstream effectors

Typical Applications

• Investigation of fertility traits in livestock

• Genetic improvement and optimization of breeding programs

• Characterization of reproductive disorders in companion and laboratory animals

• Assessment of reproductive performance under different management or environmental conditions

2. Disease Mechanism and Pathology in Animals

Methods

Discovery proteomics (DIA, 4D proteomics), PTM analysis, and protein interaction mapping.

Service Content

• Proteome profiling of disease and control animals across multiple organs or regions

• Identification of differentially expressed proteins and dysregulated pathways

• Integration of proteomic signatures with phenotype, pathology, or imaging readouts

Typical Applications

• Host response profiling to pathogens and vaccines

• Identification of protein markers associated with disease onset, severity, or progression

3. Nutritional Metabolism

Methods

Quantitative proteomics of tissues and biofluids, metaproteomics of gut contents, and targeted assays for key metabolic enzymes and transporters.

Service Content

• Comparative proteomics under different diets, feeding regimens, or nutrient compositions

• Protein level assessment of metabolic enzymes, transporters, and regulatory factors

• Correlation of proteomic changes with metabolic phenotypes such as insulin sensitivity, body composition, or energy expenditure

Typical Applications

FAQ

Q1: What types of samples are suitable?

We support a wide range of animal-derived samples, including but not limited to:

• Solid Tissues: liver, muscle, heart, brain, kidney, gonads, gut, skin, etc.

• Biofluids: serum, plasma, urine, milk, bile, cerebrospinal fluid, synovial fluid.

• Whole blood, PBMCs, isolated immune cells.

• Feces and gut contents for host–microbiota proteomics.

• Cell lines and primary cells derived from animal tissues.

If you have a special or difficult sample type, you can contact us for a feasibility discussion.

Q2: How should I prepare my samples?

1. Collect tissues quickly and keep them cold during handling

2. Do not add high levels of detergents, salts, or stabilizers

3. Snap-freeze tissues or pellets in liquid nitrogen and store at −80 °C

4. Avoid repeated freeze–thaw cycles; aliquot when possible

5. Transport samples on dry ice to maintain stability during delivery

6. Clearly label samples and provide basic metadata (species, tissue type, group, time point)

Detailed requirements and recommendations can be found in the Sample Submission Guidelines for Proteomics.

Q3: What is the service general workflow?

Q4: What data formats are provided?

1. Raw data files in instrument formats (for example .raw, .wiff, .d)

2. Protein and peptide result tables with IDs and quantification in Excel or CSV

3. Key statistical and bioinformatics outputs in spreadsheet form

4. Main figures (for example heatmaps, volcano plots, PCA) in high-resolution PNG or TIFF

5. A concise PDF report summarizing workflow, QC, and major findings

6. Additional formats can be provided on request if needed.
