Abstract

1 [3H]-prostacyclin binding to membranes of a highly differentiated neuronal somatic hybrid is increased equally in the presence of Ca2+, Ba2+, Mg2+ or Sr2+ ions. 2 Analysis of the binding of [3H]-prostacyclin in the presence of low (1 mM) or high (50 mM) Mg2+ ion concentrations has revealed a cation-dependent increase in ligand receptor affinity (Kd values = 57.4 nM and 21.9 nM). 3 The increase in [3H]-prostacyclin binding due to divalent cations is not accompanied by an alteration in the maximum binding capacity of the membranes.

摘要
  1. [3H] -前列环素与高度分化的神经元体细胞杂种膜的结合,在Ca2 +、Ba2 +、Mg2 +或Sr2 +离子存在时均有同等程度的增加。2. 在低(1 mM)或高(50 mM)Mg2 +离子浓度存在下对[3H] -前列环素结合的分析表明,配体受体亲和力存在阳离子依赖性增加(Kd值分别为57.4 nM和21.9 nM)。3. 二价阳离子导致的[3H] -前列环素结合增加,并未伴随着膜最大结合容量的改变。
