positive control in situ hybridization

[Shi-Jye Chu]

Hi:
 
   Recently I will perform in situ hybrdization in mice lung tissue,  I
want to look for a positive control biotinylated  probe for determining
the suitablity for in situ hybrdization. Do anyone know where can I get
the probe for mice from any company( I know some company had probe for
human ? Or anyone have good idea to design  the probe ?

Many thanks
