Here is the recipe I use,
a) Luminol stock: Luminol (Sigma) 4mg/ml in DMSO.
b) Enhancer stock: p-iodophenol (Aldrich) 1mg/ml DMSO.
c) Tris Buffer: 100mM Tris.HCl pH7.5
d) H2O2: 3% H2O2
Stock solns a) and b) should be kept in -20deg for <6 months.
Working soln. (Prepare just before use)
a) 0.5ml, b) 0.5ml, c) 2.5ml, d) 25ul, ddw 1.5ml (final 5ml)
This is very cheap, and as sensitive as ECL kit.
Reference: Schneppenheim et al (1991) Electrophoresis 12:367-372.
Hope this helps.
