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.

Delivery Specifications
The typical micro-scale peptide library consists of:
- Lyophilized peptides or suspended in 0.05% trifluoroacetic acid (TFA) in 50% (v/v) acetonitrile/water in Thermo Scientific Matrix 96-tube plates
- COA, HPLC and MS data for all peptides
