Abstract
We have cloned and sequenced the cDNA for the coding region of ovine alveolar macrophage interleukin-1β. At the nucleotide level, the ovine cDNA shares 95, 74 and 71 % homology with the bovine, human and murine cDNA equivalents or homologs. Comparison at the amino acid level revealed 95% homology with bovine IL-1β and approximately 57% with the human and murine homologs.
