Non-radio-isotope-detection????

[Mandy Caird PhD]

I am starting to screen some expression and non-expression libraries and I 
would like to try to do this by using non-radioactive probes.
 
On reading the bumph from:-

Amersham ECL system
BM Genius system
Promega Lightsmith systems

I am completely bamboozled as to which systems are best for what!
Does any one have any preferences regarding different company's systems 
with antibodies or oligos?  Or should I stick with P-32?

Thanks
Mandy
