Relaxin immunological activity has been observed in the plasma of pregnant bitches, and preliminary studies in our laboratory indicated that the highest relaxin concentrations were found in placentas. Therefore, canine placentas were collected at term and also from spay and relaxin was purified by methods developed for equine relaxin. Tissue was prepared by homogenization and purification on a C18 column. The preparation was further purified by stepwise elution ion-exchange chromatography, gel filtration, and gradient elution ion-exchange chromatography. One predominant peak in relaxin immunoactivity was collected. Canine relaxin was found to be larger than either porcine or equine relaxin as determined by SDS-PAGE. It migrated faster under reducing conditions, indicating a subunit structure. Purified canine relaxin was used for tracer and standard in a canine radioimmunoassay (RIA) using an antiporcine relaxin antibody. Concentrations of relaxin immunoactivity using the canine assay were up to 300-fold higher in placental preparations than those measured in the porcine relaxin assay. Sequence analysis of canine relaxin revealed a structure similar to other relaxins in the presence and placement of cystine residues.
