Quality Assurance

Our commitment to pharmaceutical-grade purity and rigorous testing standards ensures researchers receive the highest quality peptides for their studies.

≥98% Purity

All peptides undergo HPLC analysis to verify minimum 98% purity, with most batches exceeding 99% purity standards.

CoA Included

Certificate of Analysis provided with each batch, documenting purity, molecular weight, and identity verification.

cGMP Certified

Manufactured in current Good Manufacturing Practice facilities with ISO 9001:2015 certification.

Analytical Testing Standards
Every batch undergoes comprehensive analytical testing before release

HPLC Analysis

High-Performance Liquid Chromatography verifies peptide purity and identifies impurities or degradation products.

  • • Minimum 98% purity requirement
  • • Peak identification and integration
  • • Impurity profiling
  • • Retention time verification

Mass Spectrometry

MS/MS analysis confirms molecular weight and peptide sequence identity with ±0.1% accuracy.

  • • Molecular weight confirmation
  • • Sequence verification
  • • Structural integrity analysis
  • • Isotope pattern matching

Amino Acid Analysis

Quantitative analysis verifies amino acid composition matches theoretical sequence within ±10%.

  • • Composition verification
  • • Sequence confirmation
  • • Quantitative accuracy
  • • Hydrolysis optimization

Endotoxin Testing

LAL (Limulus Amebocyte Lysate) assay ensures endotoxin levels below 1.0 EU/mg for research safety.

  • • LAL chromogenic assay
  • • <1.0 EU/mg specification
  • • Batch-specific testing
  • • USP <85> compliant
Certificate of Analysis (CoA)

Each Certificate of Analysis includes detailed analytical results and batch traceability information:

Identity & Purity

  • • Product name and catalog number
  • • Batch/lot number
  • • Manufacturing date
  • • Expiration date
  • • HPLC purity percentage
  • • MS molecular weight
  • • Peptide sequence

Manufacturing Standards
Pharmaceutical-grade production in certified facilities

cGMP Compliance

All peptides are synthesized in facilities operating under current Good Manufacturing Practices (cGMP) as defined by regulatory authorities. This ensures consistent quality, proper documentation, and validated manufacturing processes.

Solid-Phase Peptide Synthesis (SPPS)

Peptides are synthesized using automated SPPS with Fmoc chemistry, providing high yield and purity. Each synthesis is followed by HPLC purification to remove truncated sequences and side products.

Quality Control

Multi-stage quality control includes in-process testing, final product analysis, and stability studies. Only batches meeting all specifications are released for distribution.

Storage & Handling

Peptides are lyophilized (freeze-dried) and stored at -20°C to maintain stability. Products are shipped with cold packs to ensure temperature control during transit. Proper storage extends shelf life to 2-3 years.
