What are common formulations for hybridization solutions?
Buffers used include 2X SSC, 5X SSPE and 50 mM PO4 (pH 7). In addition to buffer, hyb solution should contain surfactant (1-10% SDS) and blocking agent (0.5% to 1% casein). Detection systems also commonly specify other components, such as PEG or PVP, which have been found empirically to improve results.
