two hybrid validated two hybrid MI:1356 PSI-MI The protein pairs, often initially identified by a separate 2-hybrid screening methodology, are subjected to a rigorous re-analysis which may include independent re-screening of the entire search space, retesting the assay in different strain backgrounds, and multiple retesting of identified protein pairs reversing bait-prey orientations. Orthogonal data from other experimental and bioinformatic approaches may also be used to support the identification of the final high-confidence protein pairs but the primary means of selection must be experimentally based. This method would be expected to identify protein pairs with a higher degree of confidence than any single protein complementation technique. 2015-02-03T13:36:20Z orchard
