StemBeads^® Activin-A is the newest member of the StemBead^® family. StemBeads^® Activin-A offers a more efficient, cost effective way to grow Activin-A dependent cell cultures. Activin-A can be use to maintain pluripotent stem cells as well differentiate them to different lineages such as endoderm. Unlike soluble Activin-A that degrades after 12 hours in culture media, StemBeads^® Activin-A releases a constant rate of Activin-A into the culture media over 5 days creating a more stable environment allowing for:

• Fewer media changes (as little as one media change in 5 days)
• Significant savings compared to soluble Activin-A
• Significant savings on labor and media
• Easy to use: just add to your media of choice
