DMSO-FREE CRYOPROTECTANT HARNESSING NATURE AND TECHNOLOGY.

Magnus provides key elements ideal for bone formation:

  • An osteoconductive three-dimensional scaffold with cortical and cancellous components.
  • A demineralized bone scaffold with osteoinductive potential.

Does Particle Size Make a Difference?

magnus-img01

Magnus bone matrix provides a natural, osteoconductive bone scaffold composed of demineralized cortical and cancellous bone. The optimized microparticulate bone scaffold size range of 100-300 μm has been shown to induce simultaneous activity of osteoclasts and osteoblasts, demonstrating rapid healing of bone defects.

100-300 μm optimized particle size for bone regeneration has been shown to support direct ossification, with defect healing rates comparable to autograft.

Post-Thaw Cell
Characterization

Flow cytometry analysis of the cells post-thaw reveals a unique cell population optimal for osteogenic supplementation, evidenced by high expression of MSC and pluripotent cell markers.

Cell Preservation:
A Different Approach

Magnus Representative Sample

2.5% DMSO Media Sample

Industry standard DMSO penetrates and dehydrates the cell from within to prevent crystal formation. At room temperature, DMSO-based cryoprotectants raise concerns about cytotoxicity and negative effects on cell differentiation.

A Growing Body Of Evidence

MIS-TLIF study demonstrated 96% fusion at 12 months.

It All Adds Up To:

  • A natural scaffold that provides an optimal microenvironment for osteogenesis.
  • A proprietary DMSO-free cryoprotectant that allows for consistent delivery of allograft to the patient.
  • A unique cell population optimal for osteogenic supplementation confirmed through flow cytometry analysis.

Operating Room Ease of Use

  • No rinsing or decanting steps required
  • Minimum of 150,000 cells per cc of allograft5

Midfoot Arthrodesis: Patient with Multiple Comorbidities

12-week post-operative X-rays show complete osseous consolidation of the arthrodesis sites and no pain or swelling with palpation or manipulation of the surgical sites.
