Phosphopeptide Standard II

overview | features and specs | data sets | literature

Product Overview
Protea's Phosphopeptide Standards are sets of purified peptides that have been especially designed to provide high quality MS signals. Provided as lyophilized peptide mixtures, they are useful for the standardization and method development of phosphoproteomic analyses.

Phosphopeptide Standard I (PS-180) contains three singly-phosphorylated peptides, with one representative species each of serine (S), threonine (T), and tyrosine (Y) phosphopeptides.

Non-phosphorylated Peptide Partners to Standard I (PS-182) contains the corresponding three non-phosphorylated peptide partners for Phosphopeptide Standard I.

Phosphopeptide Standard II (PS-181) contains equimolar amounts of the three phosphorylated and non-phosphorylated peptides in PS-180 and PS-182.

Each Protea Phosphopeptide Standard is Certified to provide high quality signals in mass spectrometry procedures, and is provided in convenient, lyophilized vials for easy reconstitution and usage.
