Micro-scale peptide library services for proteomics research
Micro-scale peptide libraries are composed of multiple peptides containing systematic combinations of amino acids. Unlike regular peptide libraries that offer peptide quantities at a milligram scale, micro-scale peptide libraries contain peptides at micromolar scales, making them ideal for targeted proteomics applications and affordable, preliminary screening.
Common applications for micro-scale peptide libraries
Monitoring protease activity
- Identifying protease substrates using FRET
Targeted proteomics
- Selected reaction monitoring
- Analysis of protein abundance in metabolic pathways
- Assessing protein subunit stoichiometry
- Identifying phosphorylation events in signaling pathways
- Evaluating biomarker expression from serum samples
Peptide screening
- Preliminary peptide screening at a lower cost
