This approach is also advantageous in that it circumvents the laborious and often costly processes of separate protein purification and DNA cloning, since proteins are made and immobilised simultaneously in a single step on the chip surface.
Este enfoque é tamén vantaxoso porque evita os laboriosos e a miúdo costosos procesos de purificación de proteínas por separado e a clonación de ADN, xa que as proteínas son producidas e inmobilizadas simultaneamente nun só paso sobre a superficie do chip.
