The DAKO LSAB system is for use with primary antibodies produce in mouse or 
rabbit and is a labelled streptaviding-biotin system.  The LSAB2 system is also 
a labelled streptavidin-biotin system for use with primary antibodies produced 
in mouse or rabbit, but it is optimized for use with DAKO N-Series ready to use 
primary antibodies. The LSAB+ system is for use with primary antibodies 
produced in mouse, rabbit, or goat.  And I am not a salesman for DAKO just use 
a lot of their products.
