Surfactant-free preparation of an ostrich carotid artery scaffold using liquefied dimethyl ether and DNase
Instead of combining the surfactant sodium dodecyl sulphate and DNase, a combination of liquefied dimethyl ether (DME) and DNase was used to decellularise the scaffold of ostrich carotid artery tissue. Firstly, lipids were extracted from ostrich carotid artery tissue using liquefied DME at 25 °C and...
