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.

MS, HPLC and COA on 100% of peptides
Amidation, acetylation, biotin, FITC-Ahx, isotope labeling on K/R, Arg (13C6, 15N4), Lys (13C6, 15N2) and others

1.Orders which fill less than half of a plate (<48 peptides) will incur a plate fee (less than $24 total).
2.Turnaround time may be longer for difficult modifications, TFA removal, or if analytical HPLC is requested.
3.Library cost will increase by 15% if TFA removal is requested.
4.Analytical HPLC (AAA) can be requested at additional cost.
5.Modifications are available at an additional cost on a sequence-specific basis.
