iMatrix-511 Silk Recombinant Laminin E8 Fragments
iMatrix-511 stands out as an advanced extracellular matrix compatible with a diverse range of cell types. Particularly ideal for pluripotent and mesenchymal stem cells, this product features recombinant Laminin-511 E8 protein fragments. These fragments facilitate the maintenance of ES/iPS cells and MSCs in xeno-free culture environments. Moreover, iMatrix-511 supports the single-cell passaging process and offers superior adhesion compared to full-length Laminin, Vitronectin, or Matrigel.
iMatrix-511 Silk is purified from silkworm in which gene of human Laminin-511 E8 fragment is incorporated. iMatrix-511 Silk has the same functions and performance as iMatrix-511 at a more competitive pricing.
Key Features:
- Ideal for Xeno-Free, Feeder-Free Cell Culture
- Proven to provide superior adhesion of human ES and iPS cells
- Enables the passaging of single cells
- Compatible with a wide variety of cell types
- Facilitates the extended culture of hES/hiPS cells and hMSCs
- No pre-coating required
Clinical Grade iMatrix-511:
The clinical grade version of iMatrix-511, iMatrix-511MG, meets the Standards of Biological Ingredients by Pharmaceutical and Medical Devices Agency (PMDA), a government agency in Japanese that is homologous to the FDA. The regulation is one of the strictest in the world and iMatrix-511MG not only fulfils regulatory requirements, it has since been used for a number of high-profile clinical applications in Japan – Center for iPS Cell Research & Application (CiRA) Clinical iPSC Stock Project and Kyoto University Institute for Frontier Life & Medical Sciences Embryonic Stem Cell Banking Project. iMatrix-511 MG was used in the world’s first successful iPSC corneal transplantation at Osaka University.

Technical Information
Laminin-511 E8 fragment
Laminin-511, a significant constituent of the basement membrane, serves as a scaffold for pluripotent stem cells such as ES/iPS cells. As part of the basement membrane, laminin-511 (800 kDa) interacts with integrins on cell surfaces. Comprising three chains (α-, β-, and γ-chains) and forming supramolecular aggregates, laminin-511 is a notably large protein (800 kDa) that poses challenges for recombinant production. The Laminin-511 E8 fragment (150 kDa) has been identified as the smallest component capable of binding to integrins on the cell surface.
Greater Cell Adhesion & Proliferation
Human iPS cells adhere more strongly to Laminin-511 E8 fragment than to the Laminin-511 (Intact) or Matrigel.
Maintain and Culture Single ES/iPS Cells with Greater Propagation
Dispersed human single ES cells adhere rapidly to Laminin-511 E8 fragment and proliferate immediately.
Conventional culture methods often lead to cell death when ES/iPS cells are dispersed into single cells. Consequently, maintaining a cell colony becomes essential during the passaging process. However, utilizing the Laminin-511 E8 fragment as a cell culture substrate enables the successful maintenance and cultivation of even a single ES/iPS cell.
Enhance Growth of ES/iPS Cell Culture
The use of Laminin-511 E8 fragment increases the rate of proliferation as compared to the use of Matrigel.
No Pre-Cating Required
The pre-mixed method is both time-saving and cost-effective as it only requires half the amount of substrate when compared to the pre-coating method.

We recommend first trying iMatrixTM at 0.5 ug / cm2 and consider the optimal concentration to be between 0.1 and 1.5 ug / cm2. In addition, there is also a new method for plating, the Pre-mix method: Miyazaki et al. Scientific Reports, 7, 41165, 2017.
7. Is there a culture protocol for iPS cells using iMatrixTM-511?
- Please refer to the link below for the expansion culture protocol of ES / iPS cells using iMatrixTM-511（(Expansion culture protocol)）
8. Is Rock Inhibitor (Y-27632) necessary for culturing iPS cells?
- Nakagawa et al. Scientific Reports, 4(3594), 2014. Use Rock Inhibitor at cell passage. However, it is not used during medium exchange.

- Yes. iPS cell passage can be handled with a single cell. Nakagawa et al. Scientific Reports, 4(3594), 2014. * Links to the external site. （(Expansion culture protocol)）
10. What is used to detached the cells?
- We recommend using trypsin. Nakagawa et al. Scientific Reports, 4(3594), 2014. * Links to the external site. （(Expansion culture protocol)）
11. Can this product be used for mouse iPS cells?
- Currently, there is no data to support culture of mouse iPS cells using iMatrixTM-511.
12. What is the difference between iMatrixTM-511 and Matrigel?
- Matrigel contains laminin-111 from mouse EHS sarcoma. It also contains molecules other than laminin. iMatrixTM-511 is a recombinant protein purified from laminin 511-E8 fragment expressed in CHO-S cells with high purity. iMatrixTM-511 silk is a recombinant protein in which the laminin 511-E8 fragment is highly purified by silkworm-produced cocoons. Human ES cells and iPS cells are known to adhere to laminin-511 through cell membrane receptors (especially a6b1 integrin). Human ES cells and iPS cells are known to exhibit high adhesion activity to laminin-511. This makes it possible to pass iPS cells into single cells and pass them with iMatrixTM-511 / iMatrixTM-511 silk. In Miyazaki et al. (Nature communications, 3 (1236), 1-10, 2012), the expansion efficiency of the number of cells after 5 passages (after 30 days) is about 200 times higher than that of Matrigel.
