cGMP SAXS — Small‑Angle X‑Ray Scattering
Industrial SAXS testing for biopharmaceuticals and drug delivery systems. Established protocols, fast delivery, and confidential handling — not academic research.
Industrial SAXS Testing — Rarely Available Under cGMP
Unique capability: cGMP-compliant SAXS characterization is rarely available in the industry. DANNALAB offers this specialized service with the same quality systems, confidentiality, and business focus that pharmaceutical companies require.
The SAXS methodology available at DANNALAB follows the general concepts developed within the beamline communities, particularly at the European Molecular Biology Laboratory (EMBL). Most of the useful information identified by SAXS is related to the higher‑order structure, oligomeric state, aggregation pathway and conformational space of flexible systems.
Key advantage: SAXS permits the observation of objects that have not been stained or fixed, showing them in their native aqueous environment — in contrast to X‑ray crystallography, which generally requires placing the samples in non‑physiological environments.

SAXS for Biologics & Biosimilars
SAXS (and NMR) are the only laboratory methods capable of probing proteins, peptides and lipid assemblies in native solution environments — without crystallization — making them uniquely suited to study biologics and drug delivery systems.
Structural Parameters
- Radius of gyration (Rg)
- Molecular mass estimation
- Shape determination
- Oligomerization state
Higher‑Order Structure
- Ab-initio envelope reconstruction
- Conformational ensembles
- Domain organization
- Flexibility analysis
Stability Assessment
- Aggregation monitoring
- Stress testing
- Temperature dependence
- Formulation optimization
SAXS for Drug Delivery Systems
For various drug delivery systems such as liposomes, nanoemulsions, solid lipid nanoparticles, and nanostructured lipid carriers, SAXS is a valuable tool to reconstruct the nanoscale structure of the carrier.
Liposomal Formulations
- Bilayer thickness and spacing
- Lipid phase identification
- PEG corona dimensions
- Drug loading characterization
Lipid Nanoparticles (LNPs)
- mRNA-LNP assembly structure
- Particle size distribution
- Lipid organization
- Morphology determination
Nanoparticles
- Size and shape analysis
- Specific surface area
- Agglomeration effects
- Core-shell structures
