nigerin

Nigerin is a term that does not correspond to a widely recognized chemical substance, organism, or other defined entity in major reference works as of 2024. In published sources, the spelling Nigerin yields few if any stable definitions or identifiers. In practice, the term is most likely a misspelling or variant of Nigericin, or it may refer to a brand name or a non-scholarly usage. Because there is no established, citable definition for Nigerin, the article remains ambiguous without additional context.

If the intended reference is Nigericin, the following description applies. Nigericin is a polyether antibiotic produced by certain Streptomyces species. It functions as a potassium/hydrogen ionophore that dissipates electrochemical gradients across biological membranes. In biochemical research, nigericin is used to collapse the proton motive force and to equilibrate pH across membranes, enabling studies of ion transport and mitochondrial function. Nigericin is employed primarily as a laboratory tool rather than as a clinical product; it is handled under controlled conditions and is not approved as a therapeutic agent for humans or animals. It is typically supplied to researchers for in vitro assays, with attention to safety and environmental disposal.

Because Nigerin lacks a clear, verifiable definition, readers are advised to verify the term’s source or spelling. If a different meaning was intended, providing context or a source would help produce a precise article. See also Nigericin and other ionophores for related topics.
