Proteomics Peptides & Kits

Stable isotope labeled peptides (SIL peptides or heavy peptides), unlabeled peptides or absolutely quantified peptides for use as peptide standards in mass spectrometry based proteomics assays such as MRM assays. We also offer kits for assay standardization and calibration.
If you do not find what you are looking for in our shop, check our conditions for customized SpikeTides™.

Non-Quantified Peptide Sets

Sets and Pools of heavy and light peptides (e.g. TAAs, peptide hormones, cytokines, kinases).

Quantified Peptide Sets

Sets of absolutely quantified and stable isotope labeled peptides at low prices (e.g. histones, metabolic enzymes).

Quantified PTM References

Absolutely quantified proteotypic peptides and peptide collections with post-translational modifications.

Standardization Kits

Controls for mass spectrometry-based proteomics assays such as MRM assays.

The Human Proteome Peptide Catalog

1000s of reference peptides covering all human gene products.
