PRODUCT OVERVIEW

A cleaner cord blood cell product

DuxCord™ CB-MNC is processed from screened human umbilical cord blood to yield a rich population of mononuclear cells — including hematopoietic progenitors, lymphocytes, and monocytes — at a clinically meaningful dose of 30 million nucleated cells per vial.
Unlike conventional cord blood preparations, DuxCord™ achieves 99% red blood cell depletion, eliminating the primary source of post-thaw hemolysis and unwanted volume. The proprietary non-DMSO cryopreservative removes the need for washing prior to use and eliminates DMSO-related adverse reactions.
The result is a ready-to-use product with greater than 90% post-thaw viability — consistent, predictable, and optimized for applications where cell quality matters.

TECHNICAL SPECIFICATIONS

Dux Cord is a cryopreserved umbilical cord blood mononuclear cell (CB-MNC) preparation sourced from full-term, consented donations and processed under cGMP conditions. With a proprietary non-DMSO cryoprotectant and >90% post-thaw viability, Dux Cord delivers a potent, ready-to-use biologic for qualified clinical and research applications.

WHY DUXCORD™

Engineered for quality at every step
Red blood cell contamination is the leading cause of post-thaw hemolysis and alloreactivity. DuxCord™ achieves 99% depletion, delivering a visually clear, clinically clean product with reduced risk.
Our non-DMSO cryopreservative eliminates the toxicity concerns and handling complexity of traditional preservation. No wash step required before use — simply thaw and deploy.
Cell viability is validated at release, not just at time of freeze. The combination of superior RBC removal and optimized cryoformulation preserves cell membrane integrity across the freeze-thaw cycle.

REGULATORY FRAMEWORK

Manufactured under 361 HCT/P standards

DuxCord™ CB-MNC is processed under current Good Manufacturing Practice (cGMP) in a registered tissue establishment fully compliant with 21 CFR Part 1271. The product meets the criteria for regulation solely under Section 361 of the PHS Act as a minimally manipulated, homologously used human cell and tissue product.
✓ Minimally manipulated

Processing does not alter the relevant biological characteristics of cord blood mononuclear cells. Density-gradient separation and RBC depletion meet the FDA's minimal manipulation standard.

✓ Homologous use supported

Cord blood MNCs perform the same basic functions — hematopoietic reconstitution and immune support — in recipient as in the donor, satisfying the homologous use requirement.

✓ Research use

DuxCord™ is available for qualified research institutions and investigators. COAs, cell characterization data, and regulatory documentation provided upon request.

✓ Full traceability

Each vial carries a unique lot identifier with complete donor screening records, processing batch documentation, and QC release data maintained to 21 CFR Part 1271 standards.
