How is Your Baby's Cord Blood Processed?
Stem cell isolation/identification is a critical step in cord blood banking. It affects the number of stem cells that can be harvested or recovered from the cord blood. Cell recovery rates are critical because a higher number of stem cells could enhance the success of the transplant or treatment. That's why Cordlife has invested in the Sepax®2 automated stem cell processing technology which is a safe, sterile and fully automated cord blood processing technology - so you get more stem cells for maximum transplant success^.
This Swiss-made and U.S. FDA-cleared device can recover as high as 99.88%1 of Total Nucleated Cells (TNC) from cord blood; up to 57%2 cell count higher than other processing methods. It is also a functionally closed processing system which ensures the sterility of the cord blood by eliminating exposure to air contaminants.

Storing your Baby's Cord Blood
Cordlife uses U.S. FDA approved cryogenic storage pouch, with 2 integrally attached segments (20% and 80%) which are in compliance with AABB and FACT-Netcord standards. The dual integrated segments addresses the possibility for future stem cell expansion programmes. This means that when stem cell expansion technology is commercially viable, you can withdraw 80% of the stem cells for immediate use/treatment while continuing to store the 20% balance for future expansion. This storage pouch is made of a special material designed specifically to withstand cryogenic temperature at optimal cryogenic temperature of below -150°C.
The integral segments also provide the safety and assurance that additional product testing is performed on the associated unit thereby eliminating testing and cord blood unit mix ups. This is to allow for additional testing of the sample should it be required in the future, or for viability testing prior to a transplant. This storage pouch is made of a special material designed specifically to withstand cryogenic temperatures.

Cordlife also uses MVE Anti-contamination Vapour-phase Liquid Nitrogen Storage System for long-term stem cell cryopreservation.
Vapour-phase storage is preferred over liquid-phase storage as it eliminates the chance of cross contamination between cord blood units as compared with those stored in liquid nitrogen.
The MVE anti-contamination Vapour-phase Liquid Nitrogen Storage System operates perfectly, even without electrical supply, and is 100% reliable and fail-safe with no chance of robotic malfunction. Unlike other storage systems, our tanks have never been recalled by the U.S. FDA or the manufacturer
Over 99% of private cord blood banks also use vapour-phase freezers.
