MtoZ Biolabs offers Methylated Plant Proteome Analysis Service to enable systematic investigation of protein methylation across plant proteomes. This service supports comprehensive identification and characterization of methylated proteins and modification sites, providing high-quality data for studies focused on transcriptional regulation, chromatin dynamics, signal transduction, and plant stress and developmental responses.

Overview

Protein methylation is a key post-translational modification in plant systems, influencing a wide range of biological processes, from gene transcription to protein stability and signal transduction. Methylation typically occurs on lysine and arginine residues, with different methylation states such as monomethylation, dimethylation, and trimethylation. Methylation regulates important processes like chromatin remodeling, RNA metabolism, and protein-protein interactions.

Given its low stoichiometry and subtle mass shifts, detecting protein methylation at the proteome level presents challenges. Matrix interference and the coexistence of multiple methylation forms further complicate detection in plant samples. Effective enrichment strategies, combined with high-resolution mass spectrometry, are essential for confident detection and site-level annotation of methylated proteins.

FAQ

Q1: What types of samples are suitable?

Suitable samples include fresh or frozen plant tissues (e.g., leaves, roots, stems, seeds), plant cell cultures, or purified protein extracts. Plant species and tissue types across different plant species can be analyzed.

Q2: What is the service general workflow?

Q3: What data formats are provided?

We provide:

• Raw LC-MS/MS data files.

• Methylated peptide and site identification tables (CSV or Excel format).

• Quantitative analysis results (for comparing methylation levels).

• A detailed PDF report summarizing methods, quality control, and biological interpretation.

• High-resolution chromatograms and spectra in PNG or TIFF format.

Additional formats or custom outputs can be provided to meet specific research or publication needs.

Q4: How should I prepare my samples?

• For tissue samples, we recommend sending 1-2 g of fresh plant tissue for optimal results.

• Harvest plant tissues immediately and freeze them to preserve protein integrity.

• Avoid repeated freeze-thaw cycles to maintain sample quality.

• Remove any external contaminants (e.g., soil) before freezing.

• Ship samples on dry ice in sealed containers to prevent thawing during transit.

For more information, please refer to Sample Submission Guidelines for Proteomics. If you are unsure about sample preparation, our team is available for consultation and can guide you through the process to ensure optimal results.
