ECMatrix-511 E8 Laminin Substrate

Xeno-free laminin-511 coating for feeder-free pluripotent stem cell cultures, 1050 μg (CHO-S derived)

6 X 175 μg ECMatrix-511 E8 Laminin Substrate (0.5 mg/mL in PBS). Expressed in CHO-S cells.

Depending on application, either a precoating or non-precoating method can be used to culture pluripotent stem cells.

Non-Precoating Method:
1. Detach cells into small clumps or single cells using Accutase.
2. Add ECMatrix-511 to fresh media at a final concentration of 0.25 μg/cm² (for example: for one well of a 6-well plate add 5 uL of the 0.5 mg/mL stock solution).
3. Add cells to the ECMatrix-511/Media and plate the cells at desired density.

Precoating Method
1. Dilute the 0.5 mg/mL stock solution with sterile PBS to achieve a 2.5 ug/mL working solution.
2. Coat dishes with ECMatrix-511 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.

ECMatrix-511 E8 Laminin Substrates should be stored at 2-8°C. Avoid multiple freeze-thaw cycles and protect from light.
