GMP Human Laminin 511 Protein

产品描述（Product Details）

Laminin 511 E8 (LN511-E8) is a recombinant human protein that provides a defined surface for in vitro feeder-free culture of multiple human pluripotent stem cells (PSCs). Being a truncated form of laminin 511, LN511-E8 serves as a functionally minimal form that retain the full capability for binding to integrins. LN511-E8 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, LN511-E8 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. As published by Takamichi Miyazaki et al. , the LN511-E8 variant of laminin 511 shows higher efficiency for supporting the adhesion of dissociated cells than did wild-type laminin 511 which makes a cost-effective choice.
Optimized and defined surface
Laminin 511 E8 (LN511-E8) has been proved to allow single-cell seeding at low density. In a feeder-free culture system, the seeded cells demonstrate high motility with higher clonal survival.
Physiology-related
The laminin 511 isoform is crucial to the growth and maintenance of hPSCs in human through its binding to cell receptors a6B1 integrin. LN511-E8 is truncated laminin 511 isoform which works in multiple stem cell lines, from iPSC to hESC and MSC.
Better Adhesion
LN511-E8 variant of laminin 511 shows higher efficiency for supporting the adhesion of dissociated cells than did wild-type laminin 511.
Cost Effective
LN511-E8 maintains pluripotency at a lower dose without simultaneous differentiation when compared to laminin 521. Hence LN511-E8 provides a cost-effective option for feeder free culture of human pluripotent stem cells (PSCs).
Reduce Variability
LN511-E8 is a defined, recombinant human protein with better lot-to-lot consistency that reduces variability in your PSC cultures.
