| NIDS | nonionic detergent soluble |
|---|
| nonionic detergent | <chemistry> Detergent in which the hydrophilic head group is uncharged. In practice hydrophilicity is usually conferred by OH groups. Examples are the polyoxyethylene p t octyl phenols known as Tritons and octyl glucoside. Nonionic detergents can be used to solubilise intrinsic membrane proteins with less tendency to denature them than charged detergents. They do not usually cause disassembly of structures such as microfilaments and microtubules that depend on protein protein interactions. (18 Nov 1997) |
|---|---|
| nonionic surfactant | <chemistry> A surfactant without a charged moiety. (05 Mar 2000) |
| nonionic contrast medium |
A water-soluble contrast medium whose molecules do not dissociate into cations and anions in solution. These agents tend to have low osmolarity. They decrease the risk of adverse reactions, but are costly.
