Abstract

"COMPOSIçõES, MéTODOS E APARELHOS PARA CONSERVAR ESPéCIMES BIOLóGICOS E AMOSTRAS DE SANGUE SUSPEITAS DE CONTER CéLULAS TUMORAIS CIRCULANTES E, COMPOSIçãO CELULAR ESTABILIZADA". São descritos composições e métodos que minimizam perdas de células alvo (por exemplo, células tumorais circulantes) e formação de detritos e agregados de células alvo, células não-alvo e componentes plasmáticos, para estabilizar células raras em espécimes sang³íneos, conservar a qualidade dos espécimes sang³íneos e também servir como fixadores celulares, desse modo permitindo análise e classificação mais precisa das células tumorais circulantes (CTC) e, finalmente, de cargas tumorais em pacientes cancerosos. Para estabilização dos espécimes são particularmente desejáveis n protocolos requerendo enriquecimento de células raras de espécies sang³íneas extraçãos de pacientes cancerosos. Exposição de tais espécimes a condições potencialmente estressantes, encontradas, por exemplo, em processamento normal, mistura, agitação e retardos devido a transporte de sangue, tem sido observada não somente diminuir o número de CTC mas também gerar detritos e agregados nos espécimes sang³íneos que foram constatados interferir com a enumeração precisa de células alvo, se presentes. Estabilizadores são necessários para discriminar entre desintegração CTC in vivo e degradação de amostra in vivo.
