Abstract

variantes do domínio ch1 projetadas para emparelhamento preferencial de cadeia leve e anticorpos multispecíficos compreendendo as. mesmas. variantes de domínio ch1 manipuladas para ligação preferencial a um domínio kappa cl ou a um domínio lambda cl, bem como polipeptídeos, por exemplo, cadeias pesadas de anticorpos ou anticorpos, compreendendo tais variantes de domínio ch1 manipuladas e composições farmacêuticas compreendendo tais variantes de domínio ch1 e/ou tais polipeptídeos e métodos para fazer e usar tais variantes de domínio ch1 são fornecidas. as variantes do domínio ch1 minimizam o emparelhamento incorreto de cadeia pesada-cadeia leve e promovem o emparelhamento cognato de cadeia pesada-cadeia leve, melhorando assim a geração de anticorpos multiespecíficos, por exemplo, biespecíficos. também são fornecidos métodos para fazer bibliotecas de variantes de domínio ch1 e métodos para identificar uma ou mais variantes de domínio ch1.
