Our QC process

Every Alluvi Labs research batch passes through a documented analytical chemistry workflow before it leaves the facility. Identity, purity, residuals, and appearance are all verified against written acceptance criteria.

1. Synthesis & lyophilisation

Each peptide is synthesised by solid-phase Fmoc chemistry, cleaved, precipitated, and lyophilised under controlled vacuum to yield a free-flowing white powder with consistent reconstitution behaviour.

2. Identity — Mass Spectrometry

Molecular mass is confirmed by ESI-MS or MALDI-TOF against the theoretical monoisotopic mass. A batch is rejected if the observed mass deviates by more than ±0.5 Da from spec.

3. Purity — Reverse-Phase HPLC

Every batch is profiled by RP-HPLC at 220 nm against a reference standard. Acceptance criterion is ≥98.0% peak area for primary product. Chromatograms are archived with the batch record.

4. Residual solvents & water content

TFA and acetonitrile residuals are monitored by GC; Karl Fischer titration confirms moisture content is within lyophilisate spec to protect long-term stability.

5. Endotoxin & sterility screening

Selected research lines are screened by LAL assay for bacterial endotoxin and visual particulate inspection prior to vialling. For in-vitro research use only.

6. Certificate of Analysis

A batch-specific CoA is issued listing identity, purity, mass, appearance, lot number, and manufacture date. Available on request at info@alluvi-lab.com.
