    • In various embodiments methods are provided for identifying and/or quantifying one or more antigens of interest (biomarkers) on the surface of cell- or tissue-specific exosomes. In an illustrative embodiments the methods comprise: i) incubating a population of exosomes with one or more tissue-specific antibodies that bind an antigen specific to a tissue or cell type of interest that produces exosomes, where the tissue specific antibodies are attached to acceptor bead or magnetic beads so the antibodies bind exosomes displaying the antigen; ii) obtaining a purified population of exosomes bound by the tissue specific antibodies with and/or without photo-cleavable linker based technology; iii) incubating a test subset of the isolated tissue-specific exosomes with acceptor beads attached to test antibodies that bind an antigen of interest thereby binding exosomes that display the antigen of interest and a control subset with negative control acceptor beads; v) incubating the test subset of isolated exosomes and the control subset of exosomes with a donor-bearing antibody that binds an exosome specific antigen; and vi) detecting a signal produced upon illumination of the control subset and/or the test; and vii) detecting the antigen(s) of interest.
    • 在各种实施方式中,提供了用于鉴定和/或定量细胞或组织特异性外泌体表面上的一种或多种感兴趣抗原(生物标志物)的方法。 在说明性实施方案中,所述方法包括:i)将外泌体群体与一种或多种组织特异性抗体一起孵育,所述组织特异性抗体结合对产生外来体的感兴趣的组织或细胞类型特异性的抗原,其中组织特异性抗体附着于受体珠 或磁珠,使得抗体结合展示抗原的外来体; ii)使用和/或不使用基于光切割接头的技术获得由组织特异性抗体结合的外泌体的纯化群体; iii)将分离的组织特异性外泌体的测试子集与附着测试抗体的受体珠孵育,所述测试抗体结合感兴趣抗原,从而结合显示感兴趣抗原的外来体和具有阴性对照受体珠的对照子集; v)将分离的外泌体的测试子集和外泌体的对照子集与结合外泌体特异性抗原的携带有供体的抗体一起孵育; 和vi)检测在照射控制子集和/或测试时产生的信号; 和vii)检测感兴趣的抗原。
