Report verdict: Recommended interpretation: a dehydrated/powder presentation of Leibovitz’s L-15 basal cell-culture medium, hence a manufactured multicomponent formulation—not a single chemical, salt, hydrate, buffer, extract, or organism-derived material. The historical medium name is Leibovitz’s L-15 medium, also written Leibovitz L-15 medium, L-15 medium, or simply L-15. The founding pu No ontology CURIE was proposed. Recorded as provenance only — no grounding applied from this run.

Any CURIE above is a curator's to accept or reject.
