AnaSpec Introduces Acetylated and Methylated Lysines

San Jose, CA, July 28, 2007 --( AnaSpec has introduced acetylated, mono-methylated, di-methylated and tri-methylated Lysine for the synthesis of histone peptides. The use of these building blocks, although not limited to making synthetic histone peptides, provides additional tools for researchers to help unravel the “histone code.”5
The lysine-rich amino terminal tail of the core histones undergo posttranslational modifications such as acetylation and methylation.1-2 Addition of acetyl group or 1 to 3 methyl groups occur at position specific lysines.3-4 These modifications, as well as phosphorylation of serine residues and others, serve to differentially regulate chromatin activity.5
