Candidate Cellular Protein Target Identification

PD-Seq is a protocol to identify cellular targets for proteins through protein-protein interactions (Arango et al., 2013). In this method, researchers identified cellular targets for apigenin. They coupled apigenin to amino polyethyleneglycol-polyacrylamide copolymer (PEGA) beads after activation with 4-nitrophenyl bromoacetate. The apigenin-loaded beads were used for screening phage display cDNA library generated using mRNA from human breast cancer tumor cells. After 3 rounds, the fractions were used to make libraries and sequenced on the Illumina platform.
