*Comparison to top two competitors marketing literature: 60%, 70-75% (ThermoFisher's dynabeads, and Miltenyi), with multiple other primary reference sources stating 30-50% yield each pass.

Technology Application Benefits

  • Application of this next generation technology will enable access to cell therapy for more patients.
  • It will lower costs and improve quality of therapeutic and patient monitoring.
  • Fewer apheresis harvest required reducing harvest and process time
  • Speedier processes will save lives, and access for the sickest patients.
  • A triple increase in yield from a single draw moves will have significant benefits for the patient.

A Good Product Starts with Quality Cells

RBI Beads for Cell Therapy Manufacturing & Patient Monitoring

  • Our magnetic beads will reduce the loss of critical target cells in harvesting, enrichment, and in isolation/purification processes of therapeutic cells.
  • Will reduce costs and impact production time and quality.
  • Improving manufacturing will positively impacting patient access.
  • Increased cell recovery in each and every draw – results in fewer and smaller draws required from the patient.

RBI Beads can be directly applied to blood samples or Leucopaks
