Chemiluminescent substrate for alk-phos?

[Daniel Kim]

Hello:

I am using alkaline phosphatase conjugated second antibody system for 
Western blot detection.  I have been dissatisfied with the density of 
signal and photoreproducibility of NBT/BCIP color signal, and would like 
to try out a chemiluminescent system.

Is there a chemiluminescent substrate for alk phos that I could use in 
place of the NBT/BCIP system I am using now?  If possible, I would prefer 
to buy and prepare my own reagent solutions, for the sake of expenses, 
but would accept a kit recommendation if necessary.
