Running range of bromophenolblue and xylene cyanol?

[Peter Frank]

Hi,

The loading buffer for my DNA sample contains the dyes bromophenolblue
and xylene cyanol. Can anyone tell me in what bp (base pair) range
these dyes run in agarose gels for DNA analysis (i.e. DNA fragments of
what size would run along with the bromophenolblue front or the xylene
cyanol front)?

Regards,
Peter
