Unique Banking Technique

Double Stem Cell Extraction

Progenics uses the unique, modified double stem cell extraction processing technique developed by Progenics’ Research & Development Team (Yang H et al., Transfusion (2011) 51;284-292 and Yang H et al., Transfusion (2015) 55:70-78).

Cryopreservation

Progenics’ Research & Development Team works diligently at improving and perfecting the process of cryopreservation of cord blood. The cryopreservation process begins by slowly lowering the temperature of the sample using a controlled-rate freezer. Once the sample’s temperature has reached an optimal level, it is then stored in a liquid nitrogen freezer, to maintain the viability of the cells. to prevent cross contamination in storage, your cord blood is stored in a two-compartment Pall Freezing bag that is over-wrapped.

Secure Long-Term Storage

Our fire-resistant storage facility is equipped with backup generators, in the event of a power failure. In addition, the storage facility and the temperature inside the freezers are monitored 24 hours daily by security, video surveillance and environmentally monitoring and alarm systems. In case of emergencies, backup liquid nitrogen freezers are available at our storage facility which can be used immediately to transfer the contents of a dysfunctional freezer.

We use Pall cord blood collection bags which have completed an extensive sterilization process (internally and externally). It is made safe and convenient cord blood collection for vaginal births and cesarean sections. The bag is FDA NDA approved and CE marked under the Medical Devices Directive for the collection of cord blood.

At Progenics, we use Pall freezing bags which have two compartments. The cord blood stem cells can either be used for up to two transplants, or one compartment can be used for expansion, and the other for a direct transplant.

Validated Quality Assurance

Quality assessment has been validated in previous studies carried out by Progenics’ Research and Development Team.
