Acetylated Peptide Analysis Service

MtoZ Biolabs provides acetylated peptide analysis service using high-resolution LC-MS/MS platforms combined with acetylation-specific antibody enrichment strategies to accurately identify and quantify acetylated peptides in protein samples. This service is designed for research institutions and biopharmaceutical companies to systematically elucidate the role of acetylation in signal transduction, metabolic regulation, and disease progression, providing reliable support for target discovery, drug development, and epigenetic research.

 

What is Acetylation

Acetylation is a common form of post-translational modification that primarily occurs on lysine residues or at the N-terminus of proteins. This modification covalently attaches an acetyl group (–COCH₃) to amino groups, altering the protein’s charge distribution and conformation, thereby influencing its stability, activity, and molecular interactions. Acetylation plays a crucial role in regulating gene expression, chromatin remodeling, metabolic control, and signal transduction.

Acetylated peptides are peptide fragments carrying acetyl modifications, and their identification and quantitative analysis provide important insights into protein functional changes and the molecular mechanisms underlying cellular regulation and disease development.

Q3: What types of samples are suitable?

MtoZ Biolabs accepts a broad range of biological samples for acetylated peptide analysis, including:

• Cell lysates and tissue extracts

• Serum, plasma, and other biological fluids

• Purified recombinant or endogenous proteins

Samples should be of high purity and contain deacetylase inhibitors to preserve acetylation status. Avoid buffers with high salt or detergents to prevent ionization suppression in mass spectrometry analysis.

 

Q4: How should I prepare my samples?

To ensure accurate and reproducible results for Acetylated Peptide Analysis Service, MtoZ Biolabs recommends following these preparation guidelines

1. Sample Type We accept various biological samples including cell lysates tissues serum plasma and purified proteins

2. Sample Purity Samples must be free of particulates salts detergents and organic solvents that may interfere with LC separation or ionization efficiency

3. Required Amount Provide at least 100 μg of total protein at a concentration above 1 μg/μL

4. Storage and Shipping Store samples at −80°C and ship on dry ice in sealed containers to maintain sample integrity

5. Documentation Include information such as sample origin treatment conditions buffer composition and analysis objectives

 

For more information, please refer to Sample Submission Guidelines for Proteomics and Sample Submission Guidelines for Metabolomics.
