Abstract

"MéTODOS PARA ISOLAMENTO DE UMA BIOENTIDADE ALVO DE UMA AMOSTRA BIOLóGICA E DE CéLULAS DE TUMOR COM DENSIDADE DE ANTìGENO BAIXA, E, KITS PARA INIBIR A AGREGAçãO ENDóGENA DE PARTìCULAS MAGNéTICAS COLOIDAIS NO PROCESSAMENTO DE MATERIAL BIOLóGICO E, PARA ISOLAMENTO DE CéLULAS DE TUMOR DE DENSIDADE DE ANTìGENO BAIXA DE UMA AMOSTRA BIOLóGICA COM AGREGAçãO CONTROLADA DE PARTìCULAS MAGNéTICAS COLOIDAIS". Composições e métodos são divulgados que realçam a observação microscópica e análise de entidades biológicas tais como células, bactérias e vírus através de eliminação de agrupamentos magnéticos interferentes criados através de agregados naturalmente ocorrentes de partículas magnéticas coloidais. Adicionalmente os meios para realçar significantemente o isolamento magnético de células alvo de baixa densidade de antígeno de amostras biológicas são divulgados.
