Human Laminin 521 Protein, Research Grade (Flagship)

Laminin 521 offers a defined surface for feeder-free culture of human pluripotent stem cells (PSCs). It maintains normal growth and stemness in ESC, iPSC, and MSC lines. Laminin 521 supports PSC growth for over 10 passages without karyotypic abnormalities and retains differentiation ability into all three germ layers.
This product is specifically designed for academic research applications and is an alternative to basement membrane extract at No Extra Cost.
This product is designed and developed utilizing our proprietary AI technology, which is protected by patent rights. We retain full commercial rights to this product.
