Susan,

I have been using ImmPRESS lately and did a parallol staining with
HRP-Streptavidin (also from Vector). ImmPRESS is about 3-5 times more
sensitive than HRP-Streptavidin which is reported more sensitive than
Standard ABC method. A recent protocol developed is HIF-1a antibody
staining. With LSAB method HIF-1a showed no staining, but with ImmPRESS
showed strong nuclear staining pattern. Check image gallery as well for
pictures of HIF-1a staining using ImmPRESS.

Has anyone used the new "ImmPress" reagent from Vector? If so, do you
have a feel for how it compares to ABC in terms of sensitivity?

Thanks
