How do I prepare gelatin solution for plate cell culture?
Add 0.5 g gelatin (Sigma, G-1890) to sterile cell culture bottle. Add PBS to 500 mL. Autoclave (long cycle, 30 min), and let cool. Store gelatin solution at RT and use within 2 months of date of preparation. Coat tissue culture dishes for a minimum of 10 min at RT in tissue culture hood with lid on. Aspirate gelatin solution and plate cells.
Can I over-dry gelatin post coating?
Do not over-dry post coating as this disrupts the structure of gelatin and affects the attachment of cells. Prepare a 2% (w/v) solution by dissolving gelatin in tissue culture grade water.
What temperature does gelatin need to liquefy before coating?
Ensure cells are healthy and in an adequate number. Gelatin solutions need to completely liquefy at 37 C before coating. Gelatin solutions may be stored at 4 – 8 C indefinitely; elevated temperatures cause hydrolysis and loss of integrity.
What is the purpose of gelatin coating in cell culture?
I’ve been using gelatin coating standard procedures for a while, to enhance attachment/differentiation of embryonic bodies and to induce the attachment of fussy mesenchymal stem cells. I generally coat the plates/flasks with gelatine and after it, I plate my cells straight away.
