Safety warnings
Vitronectin coating
The use of Non-tissue culture-treated cultureware STEMCELL Technologies Inc. and CellAdhere™ Dilution Buffer 100 mL
STEMCELL Technologies Inc.Catalog #7183 is recommended with Vitronectin XF™STEMCELL Technologies Inc.Catalog ##07180 from the vendor.
However, we tested the use of normal tissue culture-treated cultureware and DPBS no calcium, no magnesiumInvitrogen - Thermo FisherCatalog #14190136 with Vitronectin XF™STEMCELL Technologies Inc.Catalog ##07180 , and no major differences were noted. In the protocol, we refer to this last combination.
Select extracellular matrix (ECM) according to desired culture conditions. See protocol Maintenance of hPSC for an overview on medium/matrix combinations that have been validated by CorEuStem members.
Refer to Table 1 for final volumes needed according to vessel format.

Table 2. Instructions describing reconstitution and aliquoting of vitronectin variants from different manufacturers
*Prepare aliquots according to your needs: the format we indicated for the aliquoting is enough to coat a full 6-well plate when diluted.
RT = room temperature; ON = over night
Do not store aliquots in frost-free freezer. Do not repeatedly freeze and thaw.

1h 31m
Thaw a vial of Vitronectin at Room temperature for 00:02:00 .
2m
In a 15-ml tube, dilute the Vitronectin in 6 mL DPBS, gently pipetting up and down to properly resuspend it.
Note
The indicated dilutions are for a final concentration of 5 μg/mL . Vitronectin coating has been tested and validated up to a final concentration of 3.33 μg/mL for hPSC maintenance. Optimal concentration depends on specific hPSC lines, the application or research objectives.
2m
Dispense diluted Vitronectin on the preferred dish, being careful that the surface is completely covered. If necessary, rock or tap the plate to facilitate this process. Refer to Table 1 for suggested volumes according to vessel format.
2m
Incubate the coated tissue-culture vessels for 00:30:00 to 01:00:00 at Room temperature .
1h
After incubation, aspirate the Vitronectin solution right before use, by tilting the plate and ensuring not to scrape the bottom of the well. Directly proceed with the plating of cells. Refer to Maintenance of hPSC, and/or to Single cell passaging of hPSC, Non-enzymatic passaging of hPSC. Do not allow the coated surface to dry.
Note
Vitronectin-coated plates cannot be re-used: always seed cells onto fresh Vitronectin-coated plates.
5m
If not used immediately, coated plates can be stored at 2 °C to 8 °C up to seven days.
Note
In our experience, the coating can be stored up to 30 days; however this is not suggested by the manufacturers.
For stored plates, prior to plating the cells, allow plates to equilibrate at Room temperature for about 00:20:00 and
Note
Do not allow the coated surface to dry out. To prevent excessive evaporation of the coating, tightly seal the plates with Parafilm. Additionally, some DPBS may be added after the incubation time is finished.
