Normal HRP vs Streptavidin-HRP/biotin Westerns?

[Agustin Hernandez]

Hi,

I am trying to detect a membrane protein in western blots, but, since it
is present in such ridiculous amounts in the cell, I have not been able to
do it so far. Also, because we could only tag it with a 6xHis tag,
immunoprecipitation is not very satisfactory (our antiHis antibodies are
just fair). 
I have been told that western blots based on biotinylated secondary
Ab+Streptavidin-HRP could be a solution to see this protein on western.
The guy who told me this didn't actually know much about it (and neither
do I!). Does anybody have a clear idea on how Normal secondary Ab-HRP
westerns compare to the biotin/streptavidin-HRP system? Does anyone have a
good protocol I could use? 

Thanks

A.H.
