SysQuan Human Database

Fast, large-scale absolute quantification for human samples. Unlike traditional methods requiring expensive synthetic peptides for each target, SysQuan uses metabolically K6-labeled mouse tissues with pre-quantified proteins. Simply mix your human samples with our standardized mouse tissue extracts to achieve absolute quantification across the entire proteome.

How to Use:

Search for proteins by gene name, UniProt accession, or peptide sequence
Filter by tissue type or assay availability (MRM, PRM-PASEF)
Select peptides to add them to your cart
Access MRM/PRM transitions, calibration curves, and observed peptide spectra
Download assay data

Available Data:

Optimized MRM & PRM-PASEF transitions for targeted MS
Absolute quantification calibration curves (fmol/µg)
Observed peptide MS/MS spectra from mouse tissues
Multi-tissue coverage across mouse organs

Use the SysQuan Kit: Pre-quantified K6-labeled mouse tissue extracts ready to spike into your human samples for rapid absolute quantification—no need for expensive synthetic peptide standards!
