Biolaminin 521 MX (MX521)
Human recombinant laminin 521
Biolaminin 521 MX is the natural laminin for pluripotent stem cells and therefore reliably facilitates self-renewal of human ES and iPS cells in a chemically defined, feeder-free, and animal origin-free stem cell culture system. MX521 enables efficient single-cell passaging of genetically stable and pluripotent stem cells without the need for any apoptosis inhibitors for the superior quality of your cells and studies.
A biologically relevant culture environment
Recreating the natural cell niche is key to successful cultivation. The physical, topological, and biochemical expression of the different laminin isoforms in the BM is heterogeneous and tissue-specific.
Biolaminin 521 MX (MX521-0501) is a full-length, human, recombinant laminin 521 substrate, the only one of its kind on the market, providing an optimal environment for feeder-free culture of hPSCs. Laminin 521 is a key cell adhesion protein of the natural stem cell niche, expressed and secreted by hPSCs in the inner cell mass of the embryo. The Biolaminin 521 substrate recreates a biologically relevant hPSC milieu in vitro, promoting attachment, high survival, and robust long-term self-renewal of hPSCs. In addition, the more authentic culture environment primes the pluripotent stem cells for more efficient differentiation, enhanced cell maturation, polarization and organization of specialized cell types.
The laminin 521 cell culture substrates have a positive effect on stabilizing and homogenizing pluripotent gene expression profiles between hES cell lines, providing a more controllable and robust culture system compared to the feeder- and many other feeder-free culture systems. Via the interaction with relevant cell surface receptors, laminins activate cell signaling cascades (e.g. PI3K/Akt pathway), giving consistent cellular responses and improved cell functionality, ultimately saving researchers both time and cost.
After birth, α5-laminins represent the most common laminins in the body and MX521 supports many diverse tissue cell types, such as cells from the pancreas, vascular, nervous, and muscular systems.
