Custom SpikeMix™ - Reference Peptide Pools

Quote Request
SpikeMix™ Peptide Pools are inexpensive and reliable custom stable-isotope-labeled peptide pools for relative protein quantification by mass spectrometry-based assays in targeted proteomics.

Specifications of Custom SpikeMix Peptide Pools

  • For targeted proteomics (protein detection and protein quantification by mass spectrometry)
  • Proteotypic stable-isotope-labeled peptides (SIL peptide pools)
  • Inexpensive & fast
  • Optional modifications such as Alkylation, PTMs (phosphorylation, glycosylation, methylation…)
  • All SIL peptides contain a heavy arginine or heavy lysine

Testimonials

Testimonials for Custom SpikeMix™ - Reference Peptide Pools

"At Cambridge University we have significantly benefited from a suite of SpikeTides™ from JPT which have been developed for use as organelle markers in Arabidopsis. Using these we have developed faster and more accurate methods, using SRM and PRM, for estimating organelle enrichment along linear density gradients. Results have been very instrumental in optimizing downstream methodologies, a process which has delivered improved resolution in ensuing datasets for lower costs than our original methods."
Harriet Parsons, PhD (Department of Biochemistry, University of Cambridge, UK)

"At MSKCC, we have been using JPT for isotopically labeled peptide libraries for developing pathway- and genome-scale atlases for quantitation of cellular signaling. This has been invaluable for the Quantitative Cell Proteomics Atlas (QCPA), a research tool for precise and sensitivity quantitation of cellular signaling, as well as clinical diagnostic assays for medical use."
Alex Kentsis, MD, PhD (Memorial Sloan Kettering Institue, New York, USA)
