    • The selectivity of immunoselection systems employing insolubilized avidin and biotinylated specific antibody is amplified, and nonspecific recovery is improved, by employing an indirect sandwich technique using a biotin-conjugated antispecies immunoglobulin that is directed to one or more nonbiotinylated specific antibodies in conjuction with insolubilized avidin. Specific cell populations can be removed and recovered from bone marrow, providing excellent recovery of bone marrow and preservation of hematopoietic stem cells for transplantation. Mixed populations of T cells or of tumor cells can be conveniently and simultaneously removed with minimal manipulation of the marrow cells. An improved positive immunoselection method provides viable and functional recovered cells, e.g., hematopoietic stem cells or activated killer cells, that can be clinically employed.
    • 通过使用与不结合的抗生物素蛋白结合的一种或多种非生物素化特异性抗体的生物素缀合的抗病毒免疫球蛋白的间接夹心技术,扩增使用不溶性抗生物素蛋白和生物素化特异性抗体的免疫选择系统的选择性,并且非特异性恢复得到改善。 可以从骨髓中去除和回收特异性细胞群,提供良好的骨髓恢复和用于移植的造血干细胞的保存。 T细胞或肿瘤细胞的混合群体可以方便地同时去除,同时对骨髓细胞进行最少的操作。 改进的阳性免疫选择方法提供可临床使用的可行和功能性的回收细胞,例如造血干细胞或活化的杀伤细胞。
