Specific binding of [3H]-cyclosporin C (3H-CS-C), an immunosuppressive oligopeptide, was characterized on different mouse lymphocytes. The binding was saturable, time-dependent and reversible; and KD of 1.5 x 10(-7) M and maximum binding capacity Bmax of 35 pmol/4 x 10(6) cells was found for thymocytes. A computerized analysis of the data confirmed a single population of high affinity binding sites. Lymphocytes of different organs differed in their Bmax: thymus greater than spleen greater than mesenteric lymph node (pure T cells) greater than mesenteric lymph node (pure B cells). Erythrocytes did not show a specific binding.
免疫抑制性寡肽[3H]-环孢菌素C(3H-CS-C)在不同小鼠淋巴细胞上的特异性结合得到了表征。该结合具有饱和性、时间依赖性和可逆性;胸腺细胞的解离常数KD为1.5×10⁻⁷ M,最大结合容量Bmax为35 pmol/4×10⁶个细胞。对数据的计算机分析证实存在单一群体的高亲和力结合位点。不同器官的淋巴细胞在其Bmax上存在差异:胸腺>脾脏>肠系膜淋巴结(纯T细胞)>肠系膜淋巴结(纯B细胞)。红细胞未显示出特异性结合。
