The purpose of this study was to evaluate the efficacy of a low-FODMAP diet with a concomitant reduction in tryptophan (TRP) intake in irritable … WebPCR amplification of tryptophan halogenase genes. A PCR-based method was used to screen the sponge samples for the presence and identity of potential flavin-dependent tryptophan halogenase genes. In a preliminary screening among previously reported primers, the degenerate halogenase gene targeted primers SZ002 and SZ005 (Zehner et al.
