Any protein that can be split into two parts and reconstituted non-covalently to form a functional protein may be used in a PCA. The two fragments however have low affinity for each other and must be brought together by other interacting proteins fused to them (often called "bait" and "prey" since the bait protein can be used to identify a prey protein, see figure). The protein that produces a detectable readout is called "reporter". Usually enzymes which confer resistance to nutrient de… Web7 Apr 2024 · As previously described , peptide binding validation assays to determine IC 50 values were carried out by Pure Protein LLC using the method of fluorescence polarization (FP).
