Unlocking Proteomics Possibilities: Low Cost Isotope-labeled Peptides in Proteomics

Are you in need of affordable yet reliable isotope labeled peptide standards? 

JPT has been providing market-leading innovative peptide tools to the proteomics community for many years. Besides our SpikeTides and SpikeMix platforms for tailored large-scale studies, we developed a variety of standardization kits and controls that support QC of proteomics experiments. 

We contributed to the ProteomeTools Project, examining the entire human proteome on a global scale and chemically synthesized over one million reference peptides! (Zolg et al, Nature Methods, 2017; PMID: 28135259) 

Here we proudly present the Peptide World of Discovery Proteomics: 

SpikeMix & SpikeTides Reference Peptides & Pools 

Ready to use stable isotope labeled peptides for relative protein quantification by mass-spectrometry-based assays. 

Order your custom peptides as individual peptides (SpikeTides) or as peptide mix (SpikeMix)

• for targeted proteomics
• at unmatched prices
• with optional (post-translational) modifications.
