Abstract
Abstract Several distinct peptide regions of the secreted form of purified human interleukin-1 species pI 6.8 have been found to exhibit characteristics associated with highly immunogenic protein moieties and are used to produce specific anti-peptide antibodies. The antibodies raised against the individual peptides are specific for the peptide used for their production and for IL-1, pI 6.8. The individual antibodies bind to both the precursor of IL-1, pI 6.8 and the mature or extracellular IL-1, pI 6.8.
