AuraSignal Peptides

ISO 17025 Analytical Verification • RUO Standards

Analytical Control & Quality Architecture

Every synthesized compound is subject to multi-tier analytical verification through accredited, independent third-party U.S. testing facilities before release to the laboratory directory.

Three-Point Testing Methodology

Independent confirmation of sequence identity, chromatographic purity, and sterility profile.

PURITY PROFILE

RP-HPLC Chromatography

Reversed-Phase High-Performance Liquid Chromatography at 214nm UV wavelength verifies analytical reference consistency, identifying trace isomers and synthesis byproducts.

Parameters: C18 Column • Gradient Acetonitrile/TFA • >99% Analytical Spec
MOLECULAR IDENTITY

ESI-MS Mass Spectrometry

Electrospray Ionization Mass Spectrometry calculates mass-to-charge ratios to confirm the exact theoretical molecular weight of synthesized peptide chains.

Parameters: Mass accuracy ±1 Da • Sequence verification • Zero cross-contamination
INTEGRITY ASSURANCE

Endotoxin & Bioburden Screening

Chromogenic LAL assays confirm compound isolation from endotoxins, bacterial contamination, and fungal media to ensure research reproducibility.

Parameters: Endotoxin <0.05 EU/mg • Sterile lyophilization matrix

Chain-of-Custody Verification Workflow

From solid-phase synthesis to vacuum serialization, standard protocols are tracked on every lot.

01

Automated SPPS Synthesis

Solid-Phase synthesis using Fmoc-protected amino acids guarantees precise amino acid assembly.

02

Deep Lyophilization

Sublimation under vacuum into stable, moisture-free lyophilized cakes with sealed nitrogen flush.

03

Blind Sampling

Random vials pulled from every batch are delivered in sealed custody to independent accredited U.S. laboratories.

04

CoA Digitization

Raw chromatography reports are verified, cataloged with lot numbers, and made publicly accessible.

05

Thermal-Protected Dispatch

Protected courier transport guarantees compounds arrive stable and intact at laboratory workbenches.
