Preserve & transport fresh cells, tissues & blood, without cryopreservation
The Core Technology: Permeable Alginate Hydrogel Encapsulation
Atelerix products are based on sterile, xeno-free alginate (plant-derived polysaccharide) that forms a thin, highly permeable hydrogels in seconds at room temperature. Cells, viruses, or tissues are gently mixed with the alginate solution and dispensed into vials, plates, or bags where rapid gelation occurs upon contact with calcium ions. The resulting matrix:
Mechanism of Preservation
- Immobilisation prevents sedimentation, aggregation, and shear stress
- High permeability allows O₂/CO₂ and nutrient/waste diffusion
- Hypothermic storage (4–25 °C) reduces metabolic rate by 5–10×
- No cryoprotectants required – eliminates DMSO toxicity
Key Performance Advantages
- Viability typically >90 % after 7–14 days (cell-dependent)
- Full retention of phenotype (surface markers, stemness)
- Preserved functionality in potency assays, differentiation, infectivity
- Viral vectors maintain titre; live viruses remain infectious
- Up to 80 % reduction in transport carbon footprint
