Description
Peptide Standards are lyophilized peptides that are useful for the standardization and method development of proteomic analyses. Our MultiMod PTM Standard I contains one species of each of the following post-translationally modified peptides: phosphorylated, glycosylated, sulfated, nitrosylated, nitrated, acetylated, oxidized, and methylated. Protea offers each of these modified peptides individually and also the non-modified peptide partner to each of these standards. Each Peptide Standard is Certified Mass Spec Grade and provided in convenient, lyophilized vials for easy reconstitution and usage.
