Abstract

a presente invenção refere-se a um método para detectar pelo menos uma molécula de interesse em uma amostra, compreendendo as etapas de: i) contactar a amostra com um ligante que se liga especificamente à molécula de interesse, o referido ligante sendo acoplado a um fluorocromo constituído por ficoeritrina ou um derivado seu, ii) excitar a mistura da etapa i) por pelo menos uma fonte de luz com um comprimento de onda entre 330 nm e 425 nm, iii) detectar a luz emitida pela mistura excitada na etapa ii) em um comprimento de onda maior ou igual a 550 nm, e iv) determinar a presença ou ausência da molécula de interesse na amostra com base nos resultados obtidos na etapa iii).
