abstract：:Rabbit endogenous pyrogens occurred in two forms. One was an apparently single protein with a pI of 7.3; the other was a family of proteins with pI values of 4.5 to 5.0. We selected two of the latter, with pI values of 4.6 and 4.72, as representative of the group and compared them with the pI 7.3 pyrogen. Antisera rai...
