After micro sequencing, they found a 73 amino acid chemokine, which is the protein we know as eotaxin. After more scientific research, they were able to find evidence of a human homologue of eotaxin. A primer was made from the guinea pig eotaxin in order to clone and isolate the eotaxin protein from different species.
This led to the identification of a 73 amino acid chemokine, which is now known as eotaxin. Further research uncovered evidence of a human homologue of eotaxin. A primer was constructed from guinea pig eotaxin to enable cloning and isolation of eotaxin proteins in various species.
