NUPEPS Peptides delivers peptides with purity levels exceeding 99%, achieved through advanced production technologies and a comprehensive quality-control framework.
We employ automated solid-phase peptide synthesis (SPPS) to assemble amino acids with high accuracy and reproducibility.
A gradient purification workflow is used to remove structural analogs, truncated sequences, and other impurities:
Purification conditions, including mobile-phase gradients and elution parameters, are optimized based on each peptide’s hydrophobicity, charge, and solubility profile.
Our core detection methods ensure structural accuracy and purity:
Every batch undergoes:
A consistent quality fingerprint is established using HPLC purity, MS molecular weight, solvent residues, and other analytical markers ensuring every product meets predefined purity requirements.
A high-pressure separation method that distinguishes molecules based on their interactions with the stationary and mobile phases. It offers:
An ion-based analytical technique that identifies peptides via their mass-to-charge ratio (m/z). MS enables:
Combined, HPLC + MS form the industry standard for peptide identity and purity validation. NUPEPS Peptides employs both technologies throughout production, ensuring every batch maintains exceptional analytical accuracy and consistency.
Cocer Peptides supplies peptides at ≥99% purity, suitable for advanced research and development. However, required purity depends on use-case:
We maintain strict quality control from crude synthesis to final product release to ensure each batch meets or exceeds the intended application standard.
Ideal for applications requiring the highest structural and functional accuracy:
Suitable for mid-stage research and industrial applications:
Used primarily in early discovery stages:
High-purity peptides are essential for research requiring strict structural accuracy and reliability. Cocer Peptides provides ultra-high-purity peptides (≥99%), supported by advanced synthesis, multi-stage purification, and rigorous analytical verification—ensuring every product consistently meets high scientific standards.
