NCI considers the Natural Products Repository (NPR) a national resource, and extracts from the Repository are available either in vials or in 96-well plates for distribution to qualified organizations. Each organism is extracted with a 1:1 mixture of dichloromethane and methanol, and then with water, and the extracts are stored at -200C in the Natural Products Repository at NCI-Frederick. Both extracts are tested in the NCI-60 human tumor cell line anti-cancer screen.
