| Sv | <unit> The special name for the SI unit of dose equivalent. One sievert equals one joule per kilogram. The previously used unit, rem, is being replace by the sievert. One sievert is equal to 100 rem. Abbreviation: Sv (18 Nov 1997) |

| SV40 | Symbol for simian vacuolating virus No. 40. (05 Mar 2000) |
| SV40-adenovirus hybrid | A virion consisting of SV40 genetic material encased in an adenovirus capsid. (05 Mar 2000) |
| Svedberg | <unit> A unit for measuring the rate at which a particle sediments in a centrifuge. The unit applied to the sedimentation coefficient of a particle in a high speed or ultracentrifuge. S= rate of sedimentation x 1/ rho exp2r Where rho is the speed of rotation in radians per second and r is the radius to a chosen point in the centrifuge tube. 1 Svedberg unit is defined as a velocity gradient of 10exp 13 seconds. Named after a pioneer of the ultracentrifuge. The units are nonadditive: a particle formed from two 5S particles will not have a sedimentation coefficient of 10S. (18 Nov 1997) |
| Svedberg equation | See: sedimentation constant. (05 Mar 2000) |
| Svedberg of flotation | Characteristic sedimentation behaviour of a lipoprotein fraction of plasma in a centrifugal field in a medium of appropriate density, achieved by adding a salt or D2O to the plasma. Synonym: negative S, Svedberg of flotation. (05 Mar 2000) |
| Svedberg unit | A sedimentation constant of 1 × 10-13 seconds. (05 Mar 2000) |
