M13 ssDNA-elctrphrtic species??

[Dick Beeman]

Can anyone cite a reference that discusses in detail (more detail than
found in Current Protocols) the identities of the various bands seen on
agarose gels after electrophoresis of M13 single-stranded DNA (i.e. the
supernatants after spinning cells down)?  Why does the ssDNA migrate as a
doublet with constant spacing irrespective of insert size?  What are the
critical factors in getting a good yield of this doublet without excess
contamination with the common (bacterial chromosome?) band?  Thanks!!
