Reproductively active female Bufo arenarum possess a serum protein (SBP) that binds testosterone, dihydrotestosterone, and estradiol with high affinity and capacity. The binding capacity values are two orders of magnitude higher than those found in human serum. The specificity of B. arenarum SBP is comparable to human SBP with the exception that it has a high affinity for the synthetic androgen methyltrienolone (R1881). The physicochemical characterization of SBP indicates a Stokes radius of 43.5 A, a sedimentation coefficient of 5.2 S, and a molecular weight of 93,300.
具有生殖活性的雌性阿根廷蟾蜍体内有一种血清蛋白（SBP），它能以高亲和力和高结合容量结合睾酮、双氢睾酮和雌二醇。其结合容量值比人血清中的高出两个数量级。阿根廷蟾蜍SBP的特异性与人SBP相当，只是它对合成雄激素甲基三烯醇酮（R1881）具有高亲和力。SBP的物理化学特征表明其斯托克斯半径为43.5 Å，沉降系数为5.2 S，分子量为93300。
