I've not done much comparison, but I've been using Bio-Rad's Immun-
Star substrate for years. I use it with PVDF. There's an added
enhancer for use with nitrocellulose, but I don't use NC, so I don't
now how well that works. I've found the signal very long lived.
Don't know about the price either. I don't do tons of westerns but
I've been happy with the product, so cost has not been a big issue.
We aren't set up for film anymore. We do detection with our Fotodyne
gel doc system that also does luminescent detection.

It looks like I will be doing a bunch again in the upcoming months.
Ten years is a long time and I wonder if there were any new
developments
or better/cheaper products available now.
Super-duper sensitivity is not required. Strong preference is for the
substrate that has long-living signal (I was never abale to achieve it
with home-made luminol). Low price would be nice, too. AP or HRP
- does not matter.
Oh, and what is a good inexpensive film to buy for ECL these days?
Thanks!
