ECMatrix-411 E8 Laminin Substrate

Endothelial cells line the interior surface of blood and lymphatic vessels, forming an interface between circulating blood or lymph in the lumen and the rest of tissue or organ. Laminin-411 is known to bind to the integrin α6β1 which is located on the cell surface of pluripotent stem cells and is known to induce endothelial cell differentiation. Professor Kiyotoshi Sekiguchi′s group (Matrixome, Inc.) have produced a recombinant E8 fragment of laminin-411 at large-scale while retaining the full integrin binding activity. ECMatrix-411 E8 Laminin Substrates are recombinant Laminin-411-E8 fragments which bind to integrin α6β1 and increases the differnetiuation of pluripotent stem cells (ES/iPSCs) into acetyl-LDL+/ CD31+ endothelial cells.

Xeno-free laminin-411 coating for the differentiation of pluripotent stem cells into endothelial cells, 350 μg (CHO-S derived)

350 μg (2 x 175 μg)

ECMatrix-411 E8 Laminin Substrates should be stored at 2-8°C. Avoid multiple freeze-thaw cycles and protect from light.

Precoating Method
1. Dilute the 0.5 mg/mL stock solution with sterile PBS to achieve a 2.5 μg/mL working solution.
2. Coat dishes with ECMatrix-411 at 0.25 μg/cm² (for example, for one well of a 6-well plate add 1 mL of the 2.5 μg/mL working solution).
3. Incubate for 1 hour at 37°C, 3 hours at room temperate or overnight at 4°C.
4. Before use, remove remaining fluid from the coated surface (do not rinse).
5. Detach cells into small clumps using Accutase.
6. Plate the cells at desired density.

Note: Do not allow the plates to dry, briefly spin down all liquids in the tube before use, avoid repeated freeze-thaw cycles.
