in low salt buffer in presence of molybdate ( 20 mm ) , uterine er of castrated and treated rats could not be differentiated by sucrose gradient centrifugation ( 9.9s ) , gel filtration ( 7.7 nm ) , or deae-trisacryl and phosphocellulose chromatography , but the dissociation rate at 23 c was lower for castrated than for treated rats ( t1/2 = 45 and 27 min , respectively ) .
