Abstract

<B>ENSAIO RáPIDO DE PROTEASE MICROBIAL<D>. Um ensaio para detectar atividade de protease microbial em amostras de laboratório e clínicas é descrito o qual compreende coletar uma amostra que se suspeita conter certos microorganismos tendo a atividade de protease desejada; imobilizar os microorganismos na amostra em um substrato de fase sólida; contatar os microorganismos imobilizados com um substrato enzimático produzindo um produto final de substrato enzimático; contatar o produto final de substrato enzimático com um reagente de reforço químico produzindo uma reação cromogênica detectável que varia em intensidade com o nível de atividade de protease na amostra; e detectar a reação cromogênica pelo que a presença semi-quantitativa da atividade de protease na amostra é determinada. O dispositivo para conduzir estes ensaios que é um quadro ou suporte retendo um substrato de fase sólida capaz de ligar os microorganismos de interesse enquanto permitindo drenagem de outros materiais ou fluidos, que podem conter proteases hospedeiras, no sentido oposto aos microorganismos imobilizados.
