Cold-induced phase separation for the simple and reliable extraction of sex hormones for subsequent LC-MS/MS analysis.

Journal of lipid research

Peng R, Le J, Yang SL, Cheng JR, Li Y, Wang ST.
PMID: 34863861
J Lipid Res. 2021 Dec 01;100158. doi: 10.1016/j.jlr.2021.100158. Epub 2021 Dec 01.

Sex hormones, including androgens, estrogens and progestogens, are important biomarkers for various diseases. Quantification of sex hormones is typically conducted by LC-MS/MS. At present, most methods require liquid-liquid extraction (LLE) or solid phase extraction (SPE) for sample preparation. However,...
