A novel tridentate conjugate has three chemical moieties, or tridentate members, attached through an appropriate spacer moiety. At least two of the tridentate members are relatively small molecules, usually less than about 7,000 Daltons in size. The particular appropriate spacer moiety selected for a tridentate imparts certain steric properties to the tridentate conjugate. In one embodiment, the binding of a macromolecular specific binding partner to one of the tridentate members sterically inhibits the binding of a different macromolecule to another tridentate member. In another embodiment, the binding of a first tridentate member to a macromolecule restricts the subsequent binding of a second tridentate member to a proximate location on the same macromolecule.
新型三叉共轭物有三个化学分子或三叉成员,通过适当的间隔分子连接在一起。三叉戟成员中至少有两个是相对较小的分子,大小通常小于约 7,000 道尔顿。为三叉戟化合物选择的特定的适当的间隔分子会使三叉戟共轭物具有某些立体特性。在一个实施方案中,大分子特异性结合伙伴与三叉戟成员之一的结合会立体抑制不同大分子与另一个三叉戟成员的结合。在另一个实施方案中,第一个三叉戟成员与大分子的结合限制了第二个三叉戟成员随后与同一大分子上的近似位置的结合。
