Histone Malonylation Analysis Service
Based on a high-resolution liquid chromatography-tandem mass spectrometry (LC-MS/MS) platform, the histone malonylation analysis service launched by MtoZ Biolabs provides precise detection and quantitative analysis of histone malonylation modifications. This service can identify malonylation modifications on histone lysine residues and analyze their abundance changes under different conditions. By integrating bioinformatics methods, the service provides data on modification site distribution, abundance variation, differential analysis, and functional annotation. This service offers data support for epigenetics, metabolic regulation, and cellular function studies, helping researchers explore the role of Kmal modifications in cell biology.
Overview
Histone malonylation (Kmal) is a post-translational modification in which a malonyl group is attached to histone lysine residues, and is widely related to cell metabolism and epigenetic regulation. Kmal plays an important role in chromatin structure regulation, gene transcription, and cellular responses, particularly in metabolic stress, energy balance, and cell differentiation. This service provides precise analysis of Kmal modifications, offering support for fields such as epigenetics, metabolic research, and cellular function studies, helping researchers gain deeper insights into the role of Kmal in cell biology.

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.

FAQ
Q1: How Does Malonylation Modification Differ from Other Modifications (Such as Acetylation or Methylation)?
A1: Malonylation modification (Kmal) is a relatively new epigenetic modification. Its malonyl group has a larger spatial volume and stronger polarity, which can have a more significant impact on chromatin structure compared to acetylation and methylation. Unlike acetylation, which is commonly associated with transcriptional activation, malonylation plays a crucial role in metabolic regulation, cellular response, and energy balance, giving it unique biological functions.
Q2: What Modification Sites Can This Service Analyze?
A2: We can analyze malonylation modifications on histone lysine residues, including known modification sites such as H3K9 and H3K27. Different sites may have different biological functions, so site-specific analysis is critical.
