Custom Synthetic Peptides

Service Name

Custom Peptide Synthesis Service (Research Grade & Cosmetic-Grade) — Linear / Cyclic / Modified Peptides

What We Offer

We provide end-to-end custom synthesis: sequence design review → solid-phase synthesis → cleavage/deprotection → purification (prep-HPLC) → lyophilization → QC release. You receive a ready-to-use peptide with documentation, not just raw material.

Typical Scope & Options

- Length: [2–40] AA (or up to [X] AA depending on modification)

- Scale: [0.1 mmol / 1 mmol / 5 mmol / up to X g per batch]

- Modifications supported: N-terminal acetylation / C-terminal amidation / biotinylation / phosphorylation / cyclization (amide/disulfide) / fluorescent tags (on request)

- Purity tiers: crude / 70–85% / 90% / 95% / 98%+ (by RP-HPLC)

- Format: lyophilized powder; vial/bulk; custom labeling

QC Package (standard)

- RP-HPLC chromatogram (purity)

- MS (ESI/MALDI) identity confirmation

- Residual TFA / solvents summary (where relevant)

- MSDS

Turnaround & Order Process

1) You send: target sequence + desired purity + scale + modifications

2) We confirm feasibility, provide formal quote & lead time

3) Lead time: typically [10–25] working days after sequence lock & deposit

4) MOQ: per sequence [X mg / X mmol] minimum due to setup loss

Intended Application Statement (important for compliance)

All custom peptides are supplied for laboratory research / cosmetic ingredient development unless explicitly agreed and documented under proper licensed API frameworks. We do not support unsanctioned human therapeutic use.
