The invention relates to retroviral vectors (known as lentiviral vectors), which are used to transfer genes into cells that are at cell cycle stage G0, to methods for their production and to the use thereof for transferring genes into mammalian cells. Said vectors are derived from SIVsmmPBj14 (simian immunodeficiency virus) of the sooty mangabey monkey, strain PBj 14.

Lentiviral vectors derived from SIVsmm/PBj14, method for their production and uses thereof

The invention relates to a method for producing a conductive contact part for a detachable electric plug-in connection. Said method provides a contact element comprising a bushing part, sections of which contain longitudinal slits and which has ribs distributed around its periphery. A sleeve part, which can surround the bushing part and cover the ribs, comprises two opposing end faces. The sleeve part is placed and positioned in an approximately coaxial manner in relation to the bushing part, in such a way that it covers the ribs, the positioned sleeve part being locked by one of its two faces on the bushing part. The bushing part is elastically twisted about its central axis, in such a way that the ribs are towards said central axis and the other face of the sleeve part is locked on the bushing part that is held in a twisted position against the elastic restoring force of the ribs. A contact part, designed for mass-reduction, with defined elastic properties of the ribs can thus be produced in a reproducible manner.
