  • Product Details
    Laminin 521 (LN521) is a recombinant human protein that provides a defined surface for in vitro feeder-free culture of multiple human pluripotent stem cells (PSCs). LN521 has been proven to maintain normal growth characteristics and stemness in multiple PSC lines without simultaneous differentiation, which includes ESC, iPSC, MSC etc. In addition, LN521 has been demonstrated to support PSC growth for >10 passages without any signs of karyotypic abnormalities and to maintain the ability of PSCs to differentiate into all three germ line lineages.

    Flexible & Compatible
    Laminin 521 could work well in any commercial stem cell media. Meanwhile, it could support the attachment and expansion of hPSCs both in single cells or small colonies.

    Stemness maintenance
    Laminin 521 is the biologically relevant hPSCs extracellular matrix. It is crucial for the growth and stemness maintenance of hPSCs in human through its binding to cell receptors a6β1 integrin.

    Enhance cell differentiation
    Due to the diverse biorelevant environment, laminin 521 could also enhance cell differentiation, polarization and organization of target cell types, including neuron, hepatocytes, cardiomyocytes, retinal pigmented epithelial cells, pancreatic β-cells and so on.

    Reduce Variability
    LN521 is a defined, recombinant human protein with better lot-to-lot consistency that reduces variability in your PSC cultures.
