A sensitive, specific RIA was validated and used for measurement of peripheral plasma immunoreactive inhibin (irinhibin) levels during the estrous cycle in Murrah buffalo. The RIA employed an 125-I iodinated inhibin as tracer and an antiserum against dimeric inhibin. The procedure had a sensitivity of 16 pg/tube, and the nonspecific effects of buffalo plasma were compensated for by including 200 ul bullock plasma in the standards. Separation of free and bound inhibin was affected by the use of a second antibody and precipitation with polyethylene glycol. Blood samples were collected once daily for 30 d from Murrah buffalo (n = 6) during the hot month of July. Cyclic activity and estrus were confirmed by plasma progesterone determination. Peripheral plasma concentrations of ir-inhibin fluctuated between 0.40 +/- 0.07 and 0.67 +/- 0.13 ng/ml during the estrous cycle in buffalo. During the same period, plasma progesterone levels increased from 0.21 +/- 0.01 ng/ml at Day 0 to a peak of 3.30 +/- 0.72 ng/ml on Day 13, declining sharply by Day -5. Ir-inhibin levels exhibited an increase during the follicular phase, with the maximum concentration of 0.65 +/- 0.01 ng/ml occuring on the day of estrus, a decline thereafter, and no pattern during the luteal phase. The differences, however, were not statistically significant throughout the estrous cycle.
