Rain Forest and Other Natural Products Collection

Yale Rainforest Collection is currently arrayed in 384-well plates. Extracts were created from cultures of bacterial and fungal endophytes that were isolated from rainforest plants and soil samples worldwide. This raw extract collection has been standardized to a consistent concentration but the number of components will vary with the source and extract. Confirmed hits will be subsequently subject to bio-assay guided fractionation for identification of active components.  These compounds are available, free of per assay plate charge, for use in screens by the Yale community
