antibody to luciferase commercially available?

[G.E.Fazzi]

I want to count cells after transfection with an expression vector 
including luciferase-cDNA. 

I know there are antibodies to luciferase for immunocyto- or histochemistry 
according to the literature. 
Are these antibodies already commercially available, and if they are were can 
I get them. 

Thanks,

Gregorio Fazzi
