Este artigo descreve os procedimentos experimentais para (a) esgotamento do U1 snRNP a partir de extratos nucleares, com perda concomitante de atividade de emenda; e (b) reconstituição da atividade de emenda no extrato empobrecido U1 por partículas de galectina-3 - U1 snRNP ligadas a contas covalentemente acopladas a anticorpos anti-galectina-3.
