Laminin 521, a heterotrimeric glycoprotein composed of one alpha 5, one beta 2 and one gamma 1 chain, is a defined matrix for feeder-free culture of human embryonic (hES) and induced pluripotent (hiPS) stem cells. When used in combination with defined maintenance media, Laminin 521 reliably facilitates self-renewal of human hES and hiPS cells without spontaneous differentiation.
• Supports stable self-renewal of hPSCs
• Improved recovery and survival following passage of singularized PSCs in the absence of ROCK inhibitors
• MSC and other stem cell culture
• Maintain the differentiation potential of cells in long-term culture
• Other related applications
