MtoZ Biolabs launches the Botanical Protein Molecular Weight Determination Service to support precise molecular weight characterization of plant-derived proteins through high-resolution mass spectrometry and multi-strategy separation workflows, enabling researchers in plant science, functional protein discovery, structural analysis, and mechanism studies to obtain reliable, reproducible, and scientifically interpretable molecular weight results.

The Technology of Botanical Protein Molecular Weight Determination

Common technologies used for plant protein molecular weight analysis include MALDI-TOF-MS and ESI-MS/LC-MS. These platforms differ in ionization mode, compatibility with sample complexity, and mass resolution. Researchers may select the appropriate method based on protein characteristics and analytical goals. The table below summarizes their key features and advantages in molecular weight determination:

Botanical Protein Molecular Weight Determination Service at MtoZ Biolabs

MtoZ Biolabs provides comprehensive analytical capabilities for various plant-derived samples, including but not limited to:

1. Intact Protein Molecular Weight Determination

Used to evaluate correct expression, identify truncations, processing events, or degradation fragments. Essential for plant molecular biology and genetic engineering.

2. Characterization of Natural or Bioactive Proteins

Suitable for antimicrobial proteins, signaling peptides, stress-response proteins, and other functional plant components.

3. Protein Purity Assessment and Impurity Profiling

Determines whether purified proteins contain co-extracted proteins, isoforms, or processing variants.

4. Component Screening of Complex Samples (LC-Based)

LC-MS enables refined MW analysis when protein composition is unknown or highly complex.

5. Customized Workflows for Challenging Samples

Specialized pre-treatment available for pigment-rich tissues, resinous materials, or highly fibrous plant tissues.

FAQs

Q1: What types of samples are suitable?

MtoZ Biolabs accepts a wide range of plant-derived samples, including fresh or frozen leaves, roots, stems, fruits, seeds, callus tissues, plant cell cultures, crude protein extracts, and partially purified proteins. Specialized pre-treatment workflows are available for samples rich in polyphenols, polysaccharides, or pigments.

Q2: What is the service's general workflow?

Q3: What data formats are provided?

MtoZ Biolabs offers multiple standard data formats suitable for downstream analysis and publication:

• Raw mass spectrometry files (MALDI or LC-MS)

• Molecular weight result tables (CSV or Excel)

• Spectral images and peak annotations (TIFF or PNG)

• PDF report describing experimental details, QC results, and major findings

Custom data formats can be provided upon request.

Q4: How should I prepare my samples?

To ensure accurate and reproducible results, please follow these guidelines:

1. Sample Type: Plant tissues, crude extracts, partially purified proteins, or purified proteins. For samples high in pigments, polyphenols, or resins, please inform us in advance.

2. Sample Purity: Avoid high concentrations of salts, detergents, strong organic solvents, or other components that affect ionization. For crude extracts, centrifuge to remove particulates.

3. Sample Amount: Provide enough material for repeat analysis, typically ≥100 mg of solid tissue or ≥200–500 μL of protein solution (higher concentration preferred).

4. Storage and Shipping: Store samples at −80°C and ship on dry ice using leak-proof containers.

5. Documentation: Include sample origin, preparation methods, buffer composition, and target analysis requirements for method optimization.
