It's really simple todd.  if you inject a rabbit with say, 10 ug of gp120 and
10ug of actin (say 50% contaminants in the material). the rabbit will make
antibodies to both gp120 and actin (if you put it in complete freund's
adjuvant they will also make antibodies to the dead tb bacilli it contains).

The principle you seem to be missing is you don't need pure antgens to produce
antibodies. 

Nor do you need pure antigens to measure the antibodies, although it helps.
