Abstract

Las proteínas de captura de la superficie celular recombinantes y las moléculas de detección que son útiles para aislar y detectar las células que producen una proteína secretada de interés (POI) tal como ciertas proteínas heterodiméricas que tienen un dominio CH3 de inmunoglobulina y/o un dominio CH3 sustituido. También se proporcionan proteínas de captura de la superficie celular recombinantes y las moléculas de detección que aíslan y detectan anticuerpos biespecíficos. La presente también proporciona proteínas de unión a antígenos recombinantes que son capaces de reconocer y unirse a las proteínas de interés que contienen un dominio CH3 con o sin sustituciones de aminoácidos en H95 e Y96 (IMGT). Reivindicación 1: Una proteína de unión a antígeno recombinante, caracterizada porque se une a un dominio de IgG1-Fc humano, un dominio de IgG2-Fc humano, o un dominio de IgG4-Fc humano.
