Methods for metabolites analysis in shrimp intestines

Metabolites will be extracted from shrimp intestines from T5.1. The frozen tissues will be lyophilized, ground and extracted with chloroform/methanol/water-based solution. The extraction conditions will be optimized to obtain maximum yield of the targeted metabolites involved in quorum sensing pathway. The extracted metabolites will be subjected to UPLC-MS/MS. Chromatographic separation and mass spectrometry parameters will be optimized to specific extracts to acquire the mass profiles.
