- Supplier with Internal Testing Only
- In-house UV spectroscopy
- Not disclosed
- Available on request
- No independent verification. Purity claims rely on supplier's own equipment and interpretation with no external lab confirmation
- No Testing Documentation
- None provided
- None
- Not available
- Unverifiable quality. No analytical data to confirm sequence accuracy, purity level, or contamination absence
- Third-Party HPLC Only
- HPLC-UV via external lab
- Endotoxin testing only
- Published online
- Partial verification. HPLC confirms purity percentage but lacks mass spec confirmation of molecular identity and sequence accuracy
- Real Peptides conducts small-batch synthesis with exact amino-acid sequencing, then sends samples to independent accredited laboratories for comprehensive verification. Each batch includes HPLC chromatograms showing retention time and peak purity, mass spectrometry confirming molecular weight, and amino acid analysis verifying the 13-residue sequence. Endotoxin screening uses the LAL kinetic chromogenic method with results consistently below 0.5 EU/mg. Heavy metal screening via ICP-MS confirms absence of lead, cadmium, mercury, and arsenic at detection limits of 0.1 ppm or lower.
- Suppliers performing only internal testing cannot provide the same level of verification because they lack the analytical infrastructure and third-party oversight. A supplier with an in-house UV spectrophotometer can measure absorbance at 280 nm, but this method cannot distinguish between MT-1 and structurally similar peptides. HPLC requires specialized instrumentation and technical expertise to operate and interpret. Most small peptide suppliers outsource this testing when they perform it at all.
