Studying blood
Harnessing blood as the most data rich sample type.
Discovering
Discovering low abundance markers of disease
Developing
Developing assay against the most biologically significant markers of disease.
To achieve this breakthrough,
YYZ Pharmatech has created enabling technologies that overcome three fundamental challenges:
Harness blood as the most data rich sample type
Identify low-abundance markers of disease
Develop ultra-sensitive assays against the most biologically significant biomolecules
Platform
YYZ’s integrated technology platform identifies & quantifies low-abundance markers from blood. Supported by over 20 years of research & peer-reviewed publications, YYZ’s platform is powered by
Database-Driven Proteome Intact Partition Statistical Analysis
DPiPSA™ for Discovery
Discover low-abundance & biologically significant peptides & proteins from blood or other biological samples using an unbiased & statistically rigorous bioinformatics platform. DPiPSA’s innovation is based on the novel integration of optimized sample preparation, LC-MS/MS & classical statistics.
DPiPSA is:
- Unbiased
- Statistically Rigorous
- Complementary to “omic” Methods
Applications:
- Discover New Markers for Diagnostics & Prognostics
- Identify New Therapeutic Targets
- Identify Protein Modifications & Processing
- Enable Multi Centered Clinical Drug Trials
Enzyme Linked Mass Spectrometric Assay
ELiMSA™ for Measurement
Assay low-abundance biomolecules using a quantitative detection method that reaches single molecule level sensitivity. ELiMSA’s innovation is based on the novel combination of enzyme amplification & LC-MS/MS.
ELiMSA is:
- Ultra-Sensitive
- Versatile
- Easy to Execute
Applications:
- Circulating Proteins & Peptides
- Cell-Surface Receptors
- DNA
- RNA
