detecting RNA with Southern Light kit

[kannan at kuhub.cc.ukans.edu]

Does anyone know if the southern light chemiluminescent DNA detection kit 
marketed by Tropix can be used for detecting RNA (Northern blot).  i am 
interested in knowing if the sensitivity will be the same as with Southern 
blots.

Is there a kit called Northern Light for RNA detection?

i would appreciate if someone can give some info. on this.
Thanks.
