PTMScan ® Control Peptides Pan-Methyl Lysine

Description

Designed for the PTMScan platform, this control standard features a panel of peptides with methyl-lysine modifications. It encompasses various methylation states on lysine residues, serving as a general performance monitor for assays targeting this common epigenetic mark. The 100 µl volume supports multiple quality control experiments. In mass spectrometry-based proteomics, reliable detection of lysine methylation is crucial for studying histone biology, gene expression, and other regulatory mechanisms. This pan-methyl lysine control provides reference signals that assist in instrument tuning, method validation, and the normalization of experimental runs, contributing to reproducible and confident identification of methylated peptides in complex biological samples.
