Abstract

Patente de Invenção: <B>''MOLéCULAS DE AVIDINA E ESTREPTAVIDINA MODIFICADAS E USO DAS MESMAS''<D>. São fornecidos moléculas do tipo de avidina modificada com ligação de biotina nas quais o resídio de tirosina essencial dentro do sítio de ligação de biotona é modificado em um tal modo que seu pKa é diminuído em comparação com o pka do resíduo de tirosina não-modificado na molécula do tipo de avidina não-modificada correspondente. As moléculas do tipo da avidina incluem: (i) avidina da clara do ovo natural; (ii) avidina recombinante ; (iii) formas desglicodiladas de avidina; (iv) estreptavidina bacteriana; (v) estreptadivina recombinante; (vi) estreptavidina truncada; e (vii) derivados de (i) - (Vi) os quais são modificados em sítios diferentes do resíduo de tirosina essencial. A modificação é obtida através da substituição em uma ou ambas as posições orto para os radicais hidróxi de tirosina através de radicais tais como nitro, halogeno, azo e amino. As moléculas do tipo de avidina modificada podem ser usadas em todas as aplicações da tecnologia de avidina - biotina.
