Targeted Methylation Analysis Service

MtoZ Biolabs provides Targeted Methylation Analysis Service focused on the in-depth characterization of specific methylated proteins provided by the client. This service is designed to identify and quantify methylation occurring on the client’s protein(s) of interest, revealing how these modifications influence protein structure, enzymatic activity, and regulatory function.

Leveraging advanced LC-MS/MS platforms and optimized methylated peptide enrichment workflows, MtoZ Biolabs delivers high-resolution and reproducible data for comprehensive evaluation of methylation status. Our targeted approach provides biologically meaningful insights into methylation-mediated mechanisms underlying cellular signaling, transcriptional regulation, and disease progression, supporting both academic research and drug discovery.

Overview

Methylation is a key post-translational modification that involves the addition of one or more methyl groups to amino acid residues, commonly lysine (K) or arginine (R). Protein methylation regulates a wide range of biological processes, including chromatin remodeling, gene transcription, signal transduction, and protein-protein interactions.

Analyzing methylation on specific proteins provides essential insight into molecular mechanisms that control cellular function. For instance, methylation of histone proteins such as H3 or H4 can determine whether a gene is actively transcribed or silenced. Non-histone proteins, including p53, NF-κB, and STAT3, also undergo methylation, which influences their stability, localization, and activity. By focusing on targeted proteins, MtoZ Biolabs helps researchers map methylation sites with precision, quantify modification levels, and evaluate their regulatory significance.
