| Koshland-Nemethy-Filmer model | <biochemistry, chemistry> A model to explain the allosteric form of cooperativity; in this model, in the absence of ligands, the protein exists in only one conformation; upon binding, the ligand induces a conformational change that may be transmitted to other subunits. Synonym: Adair-Koshland-Nemethy-Filmer model, induced fit model. (05 Mar 2000) |
| Kossa stain | <technique> A stain for calcium in mineralised tissue, utilizing a silver nitrate solution followed by sodium thiosulfate; calcified bone but not osteoid is stained brown to black. Synonym: Kossa stain. (05 Mar 2000) |
