phage display

Phage display is a laboratory technique where viruses called bacteriophages are used to discover molecules like antibodies or proteins that can bind to specific targets, such as disease markers. Scientists insert genetic instructions into the phages to produce these molecules on their surfaces. By exposing the phages to a target, only those with the desired binding properties stick, allowing researchers to identify and produce potential therapeutic or diagnostic agents. This method helps find highly specific molecules efficiently, advancing drug development and disease detection.
