Brown Biotech Peptide Service
Custom peptide synthesis and CDMO support — assay-ready delivery for biotech R&D teams.
Get in touchAbout us
Brown Biotech Inc. is a Korean biotech services company operating as a System of Intelligence (SoI) on top of public biomedical data. We pair custom peptide CDMO workflows with decision-ready research briefs, longevity and fibrosis pipelines, and multi-omics analysis. Our peptide service handles custom synthesis, scale-up, purity verification, and assay-ready conjugation — with Korean-language intake and 2-week typical turnaround from sequence confirmation.
What we offer
Custom peptide synthesis
5mg–5g scale, 5–70 amino acids, ≥95% purity verified by HPLC-MS. Standard or modified residues, fluorescent labels, biotin/streptavidin conjugation.
CDMO and process support
Scale-up batches (mg to g), process documentation, GMP-ready CMC packages. Method transfer and tech-support included throughout the engagement.
Assay-ready delivery
Peptide arrays, epitope mapping libraries, and pre-formatted assay plates for ELISA / SPR / cell-based screens. Turnaround 2–3 weeks.
Decision-ready research briefs
Cross-domain literature mining (PubMed, GEO, ClinicalTrials), target validation, IP landscape. Output: 8–15 page PDF + structured dataset, 5–10 business days, ₩2M–8M.
Frequently asked questions
What's the typical turnaround?
From sequence confirmation: 7–10 business days for custom synthesis (mg scale), 2–3 weeks for scale-up. Rush service available for 5-day delivery with surcharge.
Do you handle modified residues?
Yes — phosphorothioate backbone, N-methyl, D-amino acids, fluorescent labels (FITC, TAMRA, Cy5), biotin/streptavidin, and most unnatural amino acids. Contact us for non-standard modifications.
How is purity verified?
HPLC-MS by default. CoA includes chromatogram, mass spectrum, and quantified purity. ≥95% standard, ≥98% available for crystallography-grade orders.
Can you handle Korean-language intake?
Yes. Submit your sequence and specifications in Korean or English via our intake form. Korean-language support throughout the project.
