General description

Stem Cell Qualified ECM Gel is a soluble basement membrane extract (BME) purified from Engelbreth-Holm-Swarm (EHS) tumor that has been pre-qualified for human ES/iPS cell culture. The matrix polymerizes at 20-40°C to form a reconstituted basement membrane. ECM Gel contains laminin, collagen IV, entactin and heparan sulfate among other ECMs. The matrix has been extensively tested and optimized for human ES/iPS cell culture.

Features and Benefits

Eliminates the need for time-consuming prescreening and lot identification.
Provides an optimized ECM coating necessary for long term culture of pluripotent human ES/iPS cells.
Supports feeder-free culture of human ES/iPS cells in serum-free media.
Compatible with all feeder free human ES/iPS cell expansion media (i.e. mTeSR^®, PluriSTEM™)

Stem Cell Qualified ECM Gel Coating Protocol
NOTE: Expansion of human pluripotent stem cells requires culture ware that is coated with prequalified ECM proteins. Below are general guidelines for the coating of 6-well plates using the Stem Cell Qualified ECM Gel (CC131). All procedure should be performed under aseptic conditions in a biological safety cabinet.

1. Thaw the Stem Cell Qualified ECM Gel in the 2-8°C fridge one day before use. Once thawed, maintain ECM Gel on ice at all times and use pre-cooled medium and pipettes to avoid gelling of the product.

IMPORTANT: Do not thaw ECM Gel at temperatures higher than 15°C to avoid gelling.

2. Dilute the ECM Gel 1:80 with cold DMEM/F12 (D6421) medium. Scale up or down according to the volumes required. Below is an example for coating a 6-well plate with 1.5 mL of 1:80 diluted ECM Gel.

To make a 1:20 dilution, add 0.5 mL ECM Gel to 9.5 mL cold DMEM/F12 (D6421) or DMEM (D5796) medium into a 15 mL conical tube. Total volume = 10 mL.
A further 4-fold dilution is required to make the final 1:80 dilution. Add 2.5 mL of 1:20 diluted ECM Gel to 7.5 mL cold DMEM/F12 medium. Total volume = 10 mL
NOTE: The recommended dilution is 1:80, however more concentrated Stem Cell Qualified ECM Gel may be used if desired.

3. Add 1.5 mL of the 1:80 diluted Stem Cell Qualified ECM Gel to each well of a 6-well plate. Swirl the culture plates to spread the ECM Gel evenly across the surface of the plate. Store in a 2 -8°C fridge overnight or at least 2 hours in the fridge before use. If not used immediately, parafilm wrap the ECM coated culture plates and store at 2-8°C until ready to use. Use the ECM coated culture plates within 3-4 days.

4. Prior to seeding the cells, bring the plate back to room temperature for 10-15 minutes, remove the coating solution and add 3 mL/well of human ES/iPSC growth media
