Cells4Life Establishes Robust Stem Cell Viability Testing
News Dec 13, 2007
Cells4Life Ltd has, using a Personal Cellular Analysis (PCA) system from Guava Technologies Inc., established a robust testing protocol for all umbilical cord blood samples upon arrival at its laboratory before freezing.
Using the Guava® PCA system, Cells4Life is able to ensure that only samples containing a high percentage of viable (living) cells are cryopreserved for storage.
Jeff Drew, Chief Scientist at Cells4Life said, “Without the Guava® PCA system, counting of nucleated cells would be a manual process, which would be very costly in labour terms and also prone to personnel variances”. He added “The Guava® PCA system has increased the speed and reliability of our in-house viability testing and it also usefully provides a hard copy report in a format easily understood by non-technical staff and customers”.
The ultra-compact size makes the Guava® PCA system indispensable to all scientists who need immediate access to simple cell monitoring and screening assays. Intuitive in operation, the Guava® PCA can provide precise and easy-to-read results with often less than one day of training.
Increased cell counting accuracy on the Guava® PCA translates into evaluation of percentage viable stem cells in samples prior to cryopreservation. Benefiting from a patented self-aligning, user-replaceable microcapillary flow cell - assays on the Guava® PCA need less cells (< 20 µl), less reagents and generate minimal waste.
