Abstract

Patente de Invenção: <B>"PROCESSOS E MATERIAIS PARA OTIMIZAçãO DE REAçõES DE HIBRIDIZAçãO ELETRôNICA"<D>. As seguintes invenções referem-se às descobertas relativas a vários parâmetros, eletrôlitos (tampão) e outras condições, que aperfeiçoam ou otimizem a velocidade de transporte de DNA, a eficiência das reações de hibridização de DNA e a especificidade de hibridização global em chips e dispositivos microeletrônicos. Em particular, esta invenção refere-se à descoberta de que soluções de tampões zwitteriónicos de baixa condutância, especialmente aquelas contendo o aminoácidos histidina preparado, em concentrações de <sym> 50 mM no, ou próximo do, pl (ponto isoelétrico <sym> pH 7,47), proporcionam condições ótimas para ambas as reações de transporte de DNA eletroforético e hibridização eficiente. As eficiências de hibridização de pelo menos um fator de 10 em relação ao tampão melhor conhecido seguinte, cisteína, são obtidas. Os dados dos testes demonstram um aumento de aproximadamente 50.000 vezes em eficiência de hibridização, comparadas com a cisteína.
