PTMScan ® Control Peptides Symmetric Di-Methyl Arginine

Description

A set of synthetic peptides containing symmetric di-methyl arginine modifications, this product functions as a control standard for the PTMScan platform. Symmetric dimethylation of arginine residues is a specific epigenetic mark associated with transcriptional regulation and RNA processing. The provided 100 µl quantity is used to benchmark mass spectrometry performance for detecting this precise modification. These control peptides enable researchers to confirm that their instrumentation and protocols can accurately identify and distinguish symmetric di-methyl arginine from other related forms, such as mono-methyl or asymmetric di-methyl arginine. This validation is essential for generating high-quality, interpretable data in proteomic studies of arginine methylation.
