MtoZ Biolabs launches Plant Protein Gel and Image Analysis Services to deliver standardized electrophoresis workflows and digital imaging analyses that support protein separation, molecular weight determination, purity evaluation, and expression profiling of plant-derived proteins. The service enables researchers to obtain clear, interpretable, and comparable band data that enhance the overall efficiency of plant studies and downstream experimental workflows.

Plant Protein Gel and Image Analysis Services at MtoZ Biolabs

Plant tissues contain polysaccharides, phenolic compounds, pigments, and other complex components that often interfere with protein separation and imaging, leading to unclear bands, high background, and poor reproducibility. MtoZ Biolabs has established a standardized gel electrophoresis and image analysis workflow optimized for plant proteins, including:

1. SDS-PAGE-Based Plant Protein Separation

SDS-PAGE is commonly used to separate plant proteins of different molecular weights. It provides clear band patterns for size determination, expression verification, and purity assessment, and can be combined with mass spectrometry-based identification for profiling complex plant protein samples.

2. 1D SDS-PAGE and Isoelectric Focusing (IEF)

1D SDS-PAGE separates proteins by molecular weight, while IEF separates proteins by isoelectric point. The combination achieves higher resolution and is suitable for expression analysis, quality monitoring, and structural investigation of plant proteins.

3. Two-Dimensional Gel Electrophoresis (2-DE)

2-DE separates proteins based on both isoelectric point and molecular weight, making it valuable for analyzing protein composition and isoform distribution in plant tissues. It supports comparative studies between treatment and control groups, as well as research on cellular states and stress responses.

4. 2D Blue Native / SDS-PAGE Protein Complex Analysis

Blue Native PAGE preserves the native conformation of protein complexes, enabling analysis of plant protein subunits and complex stability. When combined with SDS-PAGE in the second dimension, it provides detailed information on complex organization, useful for studying signaling proteins, membrane complexes, and energy-related protein assemblies.

5. Western Blot Analysis

Through membrane transfer and antibody-based detection, Western blot supports qualitative and semi-quantitative analysis of target proteins and post-translational modifications. It is widely used for expression validation, pathway studies, and functional characterization of plant proteins.

FAQs

Q1: What types of samples are suitable?

Plant leaves, roots, stems, fruits, seeds, callus tissues, plant cell cultures, crude protein extracts, and purified proteins.

Q2: What is the service's general workflow?

Q3: What data formats are provided?

MtoZ Biolabs provides multiple standard data formats to support downstream visualization, comparison, and record-keeping needs. Deliverables typically include:

• High-resolution gel images (TIFF or PNG)
• Processed analysis files (Excel or CSV) with band identification, grayscale values, and relative expression levels
• A PDF summary report including electrophoresis conditions, imaging methods, analysis workflow, QC information, and key results
• Optional raw image files for verification or re-analysis

If needed, MtoZ Biolabs can provide additional file formats or reorganize data structures to meet publication or project-specific requirements.

Q4: How should I prepare my samples?

To ensure accurate and reproducible gel and image analysis, MtoZ Biolabs recommends preparing samples according to the following guidelines：

1. Sample Type: We accept plant tissues, crude protein extracts, partially purified proteins, purified proteins, and plant cell cultures. If samples contain pigments, polysaccharides, or phenolic compounds, please inform us in advance so that appropriate pre-processing can be applied.

2. Sample Purity: Samples should be free of particulates and high levels of salts, detergents, or strong organic solvents that may interfere with electrophoresis or staining quality. For crude extracts, centrifuge samples to remove debris before submission.

3. Sample Amount: Please provide sufficient material for gel loading and replicate analysis. Generally, solid tissues ≥100 mg, and liquid protein samples ≥200–500 μL are recommended.

4. Storage and Shipping: Store samples at −80°C. Ship samples on dry ice in sealed, leak-proof containers to maintain protein integrity.

5. Documentation: Include sample origin, preparation method, buffer composition, expected protein size range, and intended analysis type to ensure proper workflow selection.
