    • The present invention relates to novel methods for detecting a member of a known binding pair in a sample, including a cell, where one member of the pair (termed the "receptor") is expressed by a bacteriophage, which phage is then used to detect the presence of the other member of the pair (termed the "ligand" or "target"). Rather than detecting the binding of the phage using antibody-based technology, the present invention relates to detecting marker molecule associated with the phage. In one aspect, the invention relates to identifying an antigen-bearing moiety (e.g., a red blood cell antigen) of interest present on a cell, e.g., a. red blood cell, using antibody- displaying bacteriophage, as well as detecting anti-red blood cell auto- or alloantibodies and/or complement in a sample, using antiglobulin reagent-displaying bacteriophage and detecting a marker molecule associated with the phage. In one aspect, the phenotype of the phage is not linked with the genotype of the phage.
    • 本发明涉及用于检测样品中已知结合对的成员的新方法,包括细胞,其中一对成员(称为“受体”)由噬菌体表达,然后使用该噬菌体检测 该对的另一成员的存在(称为“配体”或“靶”)。 本发明不是使用基于抗体的技术检测噬菌体的结合,而是检测与噬菌体相关的标记分子。 一方面,本发明涉及鉴定细胞上存在的感兴趣部分(例如,红细胞抗原),例如, 红细胞,使用抗体展示噬菌体,以及使用抗球蛋白试剂显示噬菌体和检测与噬菌体相关的标记分子来检测样品中的抗红细胞自身或同种异体抗体和/或补体。 一方面,噬菌体的表型与噬菌体的基因型不相关。
