Bolton-Hunter试剂n-琥珀酰酰3-(4-羟基,5-[125I]碘苯基)丙酸,作为两栖动物和被囊动物胚胎发育和分离细胞(人红细胞和培养的鸡肢体间充质细胞)的重要染色剂。我们发现,Bolton-Hunter试剂可以在室温下用于活细胞,其技术与体外常规用于标记分离大分子的技术非常相似。在足以标记完整细胞中的细胞内蛋白的浓度下,标记的细胞经历正常的发育序列。在这些条件下,Bolton-Hunter试剂的生命染色不成比例地标记外部蛋白质,Bolton-Hunter试剂似乎是细胞表面和细胞膜蛋白质的特别好的生命染色剂。博尔顿-亨特染色是共价结合的,不可重复利用,似乎不会破坏自然生理和发育过程。因此,我们使用Bolton-Hunter试剂来跟踪蛋白质在体内的自然寿命,我们能够在爪蟾胚胎中区分出特别长寿的蛋白质。
The Bolton-Hunter reagent,N-succinimidyl 3-(4-hydroxy, 5-[125I]iodophenyl)propionate, was used as a vital stain for developing amphibian and tunicate embryos and for isolated cells (human erythrocytes and cultured chick limb mesenchymal cells). We found that the Bolton-Hunter reagent can be used on living cells at room temperature with techniques that are quite similar to the techniques routinely used to label isolated macromoleculesin vitro. At concentrations of vital stain that were sufficient to label intracellular proteins in intact-cells, labeled cells underwent normal developmental sequences. Under these conditions, vital staining with the Bolton-Hunter reagent disproportionately labeled exterior proteins, and it seems likely that the Bolton-Hunter reagent is an especially good vital stain for cell surface and cell membrane proteins. The Bolton-Hunter stain is covalently bound, is not reutilizable, and appears not to disrupt natural physiological and developmental processes. Thus, we used the Bolton-Hunter reagent to follow the natural life spans of proteinsin vivoand we were able to distinguish particularly long-lived proteins inXenopusembryos.
