Reverse hemolytic plaque assay

[Dr. Shoumo Bhattacharya B1 061]

Hi
I am trying to assay the secretion of a protein in mammalian cell culture, and 
am trying to set up a reverse hemolytic plaque assay for it. What is the 
maximum protein size that can be assayed by this method? Can anyone give me any
tips for this assay?  Can it be done in petri-dishes or does it have to be 
done in Cunningham chambers?

2.	Also has anyone made a successful fusion protein with luciferase or
beta-galactosidase with your protein of interest in order to detect its secretion in
cell culture?  This would avoid fiddling about with antibody and complement
etc.

I'd appreciate any comments and help.

Thanks
