Histone Monomethylation Analysis Service
Based on a high-resolution liquid chromatography–tandem mass spectrometry (LC-MS/MS) platform combined with specific modified peptide enrichment methods, the histone monomethylation analysis service launched by MtoZ Biolabs enables precise detection and quantitative analysis of monomethylation modifications on lysine or arginine residues of histones. This service can identify monomethylation modifications at different sites and monitor their abundance changes under different experimental conditions. By integrating bioinformatics approaches, it provides high-quality data on modification site distribution, differential comparison, and functional annotation, offering reliable support for in-depth analysis of the functional characteristics of monomethylation.
Overview
Histone monomethylation (me1) refers to a type of post-translational modification in which a single methyl group is attached to lysine or arginine residues of histones, mainly occurring on the N-terminal tails of histones H3 and H4, and it plays an important role in maintaining chromatin structure and regulating gene transcription. Monomethylation is critical in biological processes such as chromatin remodeling, gene expression regulation, cell cycle control, as well as development and differentiation. Histone monomethylation analysis enables systematic detection and quantitative evaluation of monomethylation modifications at different sites, with broad applications in epigenetic research, cellular function studies, and potential biomarker discovery, providing reliable data support for understanding the role of monomethylation in life processes.

Sample Submission Suggestions
1. Sample Type and Quantity

Note: Plasma should be collected using EDTA as an anticoagulant. Standard tissue or cell lysis buffers can be used during protein extraction.
2. Sample Transportation
Avoid repeated freeze-thaw cycles. Samples are recommended to be stored at -80°C and transported on dry ice to ensure low-temperature conditions throughout the process and prevent modification loss.
Note: For special samples or if a detailed submission plan is required, please contact MtoZ Biolabs technical staff in advance.
