reagent for titering baculovirus

[Song Tan]

I vaguely remembering seeing an ad describing a reagent (probably an
antibody) to speed up determination of baculoviral titers.  Problem is, I
don't remember where I saw the ad and I can't remember the company.  Could
anyone who remembers the ad please give me a lead, even better, could
someone who has tried it please rate the product?

Many thanks!
