JPT's Histone Code Peptides
As histones are a major focus of epigenetics, JPT's computational scientists compiled a unique library of synthetic posttranslationally modified and unmodified human histone peptides that is now available as individual biotinylated peptides. The peptide library consists of more than seven hundred 20mer peptides from 29 histone families (e.g. H2A[1,19,85...], H2B[1,22,42...], H3[1,23,43...], H4[1,14,44...]). Peptides carry PTMs at reported sites (e.g. acetylation, methylation, phosphorylation, citrullination) in various combinations representing natural variants.
JPT's highly skilled and committed scientific staff ensures that the most appropriate methods and techniques are selected for every synthesis project. All of JPT's catalog peptides are provided with HPLC-MS analyses to confirm the identity and demonstrate the high quality of our peptides.

Benefits of JPT's Histone Code Peptides
- Whole production performed in a regulated European environment according to DIN EN ISO 9001:2015 & GCLP standards; audits welcome!
- For high-throughput screening the whole Histone Code Peptide library is also available displayed on peptide microarrays
- Provision of freeze dried aliquots for enhanced stability
- Proven track record for many applications

Testimonial for Histone Code Peptide Microarray
"JPT's new extremely high-density histone peptide array is a dramatic leap forward for analysis of the histone code hypothesis. The complete sequence coverage across core histones and histone variants as well as the presence of common and rare histone post-translational modifications "alone and in combination" makes this an unparalleled tool for studying the "writers" and "readers" of the histone code. My laboratory has used these arrays to ask the sequence and PTM dependence of a histone writer enzyme and we have discovered an activity specifying code that will keep us busy for years to come."
