Relaxin activity in the pregnant cat

DR Stewart and GH Stabenfeldt

Plasma relaxin activity was measured by radioimmunoassay (RIA) in the domestic cat utilizing two different antisera developed against highly purified porcine relaxin. One was the 5858 antiserum from our laboratory and the other was the R6 antiserum of Dr. Bernard Steinetz. Relaxin activity could not be detected during the estrous cycle or during pseudopregnancy. Relaxin immunoactivity during early gestation was not detected by either antiserum. Plasma relaxin immunoactivity was first detected by both antisera on about Day 25 of gestation. Relaxin concentrations then increased rapidly, with a plateau reached between Days 30 and 35 that was maintained until 10-15 days prepartum. Relaxin concentrations then declined gradually until parturition. No prepartum increase was observed. Relaxin concentrations were undetectable within 24 h of delivery. Although amounts of immunoactivity measured with the R6 antiserum were consistently higher than measurements with the 5858 antiserum, the patterns of secretions observed were similar for both antisera.
