Analysis of defective SV40 DNA by agarose gel electrophoresis. 1975

C J Sol, and C Walig, and J ter Schegget, and J van der Noordaa

The SV40 DNA that was generated by undiluted passaging of the virus was analysed by agarose gel electrophoresis. Nine bands of virus DNA were distinguished and each band contained a specific size class of DNA, all shorter than the complete SV40 genome as was determined by electron microscopy measurements. A difference of 2% in length, about 100 base pairs, resulted in a clear band splitting. Two sets of undiluted passaging were established and the defective DNA in the two sets had both different and similar size classes varying in length from 96% to 73% of the unit length SV40 DNA.

UI MeSH Term Description Entries
D008970 Molecular Weight The sum of the weight of all the atoms in a molecule. Molecular Weights,Weight, Molecular,Weights, Molecular
D002460 Cell Line Established cell cultures that have the potential to propagate indefinitely. Cell Lines,Line, Cell,Lines, Cell
D003673 Defective Viruses Viruses which lack a complete genome so that they cannot completely replicate or cannot form a protein coat. Some are host-dependent defectives, meaning they can replicate only in cell systems which provide the particular genetic function which they lack. Others, called SATELLITE VIRUSES, are able to replicate only when their genetic defect is complemented by a helper virus.
