Después de la realización de la PCR, los productos se purificaron a partir de todas las soluciones de la reacción mediante el uso del kit de purificación de PCR QIAquick (Qiagen) a través del procedimiento descrito en el manual de instrucciones adjunto, y se eluyeron mediante el uso de agua esterilizada. Después de que se digirieron los fragmentos con la enzima de restricción Sfi I (TOYOBO), se sometieron a electroforesis en gel de agarosa al 2%. 5 Los fragmentos de amplificación que tienen aproximadamente 0,4 kb se purificaron mediante el uso del kit de extracción en gel QIAquick (QIAGEN) a través del procedimiento descrito en el manual de instrucciones adjunto y se eluyeron mediante el uso de agua esterilizada. Los fragmentos obtenidos se ligaron mediante el uso de alta ligación (TOYOBO) con el vector de expresión de cadena L descrito anteriormente pCAGG-κ que se había digerido con Sfi I. Se utilizó parte de cada solución de reacción para transformar la cepa DH5 α E. coli (TOYOBO). Se determinaron las 10 secuencias de nucleótidos y se confirmaron mediante el uso del kit de secuenciación BigDye Terminator Cycle (Applied Biosystems) con el secuenciador de ADN ABI PRISM 3700 DNA Sequencer (Applied Biosystems) de conformidad con el procedimiento descrito en el manual de instrucciones adjunto. pCAGG-A44BBA se obtuvo mediante inserción del fragmento BBA y otros vectores de expresión se obtuvieron de forma similar mediante inserción de otros fragmentos VL. Las secuencias de región variable de anticuerpos correspondientes se describen 15 en las siguientes SEQ ID NO. Tabla 2
