Abstract

methods of detecting donor-specific antibodies and systems for practicing the same abstract: provided are methods for determining the presence or absence of donor specific antibodies in a biological sample. the methods include mixing a cellular sample from a donor with a biological sample from a recipient under conditions sufficient for recipient immune antibodies, if present, to bind to donor cell surface antigen (ag) to form an immune antibody-ag complex, contacting the mixture with beads comprising an antibody that specifically binds the immune antibody-ag complex (e.g., the ag or immune antibody) on a surface thereof, adding under lysis conditions a detectably-labeled antibody that specifically binds the immune antibody-ag complex bound to the beads, and detecting the presence or absence of the detectably-labeled antibody bound to the immune antibody-ag complex to determine the presence or absence of donor specific antibodies in the biological sample from the recipient. systems and kits for practicing the subject methods are also provided. tradução do resumo resumo "métodos para detecção de anticorpos para doadores específicos e sistemas para pratica destes" são apresentados métodos para determinar a presença ou ausência de anticorpos específicos ao doador in uma amostra biológica. os métodos incluem misturar uma amostra celular a partir de um doador com uma amostra biológica a partir de um recipiente sob condições suficientes para anticorpos imunológicos do recipiente, caso presente, para ligar ao antígeno de superfície de célula doadora (ag) para formar um complexo de anticorpo imunológico ag, por em contato a mistura com microesferas que compreende um anticorpo que se liga especificamente ao complexo de anticorpo imunológico ag (por exemplo, o ag ou o anticorpo imunológico) em uma superfície do mesmo, adicionar sob condições de lise um anticorpo detectavelmente marcado que se liga especificamente ao complexo de anticorpo imunológico ag ligado às microesferas, e detectar a presença ou ausência do anticorpo detectavelmente marcado ligado ao complexo de anticorpo imunológico ag para determinar a presença ou ausência de anticorpos específicos ao doador na amostra biológica a partir do recipiente. os sistemas e os kits para praticar os métodos também são fornecidos.
