lipidomics profiling


service description

bgi genomics lipidomics profiling services are designed to obtain a lipid profile and screen for differentially-expressed lipids in the sample. bgi has extensive experience in the field of lipidomics profiling with developed reliable workflows using market leading technologies and an advanced bioinformatics infrastructure¹.

lipidomics profiling

combined with lipidsearch software and advanced algorithm analysis, bgi's lipidomics profiling service enables confirmation of lipid structure characteristics such as lipid molecule head structure, fatty acid branch chain length and unsaturated double bond number by comparing the characteristic signals of precursor ions, ms2 fragments and neutral loss. lipidsearch is equipped with the largest lipids database, covering 8 categories of lipids, 300 lipid subclasses, and containing more than 1.7 million lipid ions and their predictive fragment ions information.
