If you have already cloned the splice variants you want to look at,
you could delete the parts of the cDNA that code for all variants 
and use the splice-form-specific bit to make your probe (just don't 
hydrolyze the shorter probe as long.)  

Also, making probes from introns using cloned genomic fragments works,
if an intron or 3'UTR is variant in the isoform you want to look at.  
Let the development reaction go longer and your intronic probe will
label nuclei (but not cytoplasm).
