Histone Modification Analysis Service

Histone Modification Analysis Service

Service Details


Histones are a class of highly conserved proteins with many types of histone modifications, including acetylation, methylation, ubiquitination, citrullination, and phosphorylation of specific amino acids within histones. The analysis of these covalent modifications can provide valuable information for the study of diseases such as cancer.

Genomics and mass spectrometry is most widely used for histon analysis. Notably, Mass spectrometry typically is the technique of choice for the discovery and quantification of histone PTMs with high sensitivity analysis due to combine high speed (scan rate >10 Hz), high resolution (> 60,000), and combine MS acquisition with online separation techniques such as nano-liquid chromatography. so taht it can be used in a quantitative manner for comparative analysis of protein expression levels as well as differential expression analysis of protein modifications.

Our Services

Creative Proteomics has launched a dedicated histone modification analysis platform with advanced mass spectrometer and Nano-LC for histone modification analysis services on the basis of extensive experience in mass spectrometry.

At Creative Proteomics, our highly qualified scientists provide you with professional histone isolation and purification technology to obtain high-purity histones for mass spectrometry analysis, while preserving post-translational modifications (PTMs) of histones. In order to reduce the generation of small hydrophilic peptides by tryptic proteolysis below the mass dynamic range of the MS detector and to identify and quantify more information on histone post-translational modifications, chemical derivatization is used as a means of increasing the hydrophobicity of the peptides during the digestion process. In addition, 2-3 different enzymes are used by our scientists to digest protein samples, thus improving the sequence coverage of histone MS peptide maps to identify more PTM sites.

With cutting-edge equipment and expertise in protein sequencing and mass spectrometry, we provide one-stop histone modification analysis service. You only need to tell us the purpose of your experiment and send your samples to us, we will take care of all the follow-up matters of the project.
