RevitaCell™ Supplement (100X) has been optimized for use with pluripotent stem cells (PSCs), either as a post-thaw recovery solution to improve cell viability or in combination with Essential 8™ Medium to enhance single cell passaging applications. It can also be used for recovery of primary neurons, traditionally a challenging cell to efficiently recover. The significant improvement seen in these applications is due to the presence of a more specific ROCK inhibitor coupled with molecules containing antioxidant and free radical scavenger properties that minimize the impact of stress on the cells.

• • Enabling—provides maximum cell viability when performing single cell passaging

n

• • Rapid cell recovery—high post-thaw cell viability and growth of pluripotent stem cells (passaged as clumps or single cells) and neurons

n

• • Consistent—formulated using animal origin-free and chemically defined materials for quality and confidence
    
    Single cell passaging
    Use of the RevitaCellTM Supplement for 18-24 hours post-single cell passaging provides vast improvement in cell survival. Cells are shown to reach passaging confluency within 3-4 days post-seeding.
    
    Higher specificity
    Kinase profiling of pro-survival small molecules in RevitaCell™ Supplement shows higher specificity in comparison to traditional ROCK inhibitors (i.e., Y-27632 and Thiazovivin).
    
    Quicker post-thaw recovery
    PSCs recovered at 40,000 viable cells/cm² using media supplemented with RevitaCell™ Supplement for the first 24 hours post-thaw recovery followed by feeding with unsupplemented Essential 8™ Medium will typically reach 80% confluency in <5 days, significantly reducing the average post-thaw recovery time of most cryopreservation solutions. Neurite outgrowth of neurons is also significantly improved using RevitaCell™ Supplement.
