Dako make both kits.
The enVision kit is an amplification kit, which uses a Dextran backbone, to
enable large numbers of substrate molecules to bind to the secondary
antibody.

The LSAB kit (labelled Streptavidin-Biotin ) has a primary, a biotinylated
secondary, and then an enzyme conjugated streptavidin reagant.  Again, it is
a senistive amplification kit...

Both kits can be used with mouse/rabbit primaries, and either an HRp or AP
substrate...

Hope this helps!

(i dont work for Dako, hence i am not 100% sure i ahve got it right...i just
ahve a lot of their info!!)
