RT Journal Article T1 Tracing (r)bST in cattle: Liquid-based options for extraction and separation A1 Regal López, Patricia A1 Lamas Freire, Alexandre A1 Fente Sampayo, Cristina Asunción A1 Franco Abuín, Carlos Manuel A1 Cepeda Sáez, Alberto K1 rbST K1 Bovine K1 Somatotropin K1 Liquid chromatography K1 Extraction K1 Separation K1 Cattle AB Growth hormone (GH) or somatotropin (ST) is a species-specific polypeptide hormone produced in the pituitary gland of vertebrates. When administered exogenously to dairy cattle, it has galactopoietic effects and is capable of increasing the milk yield. Recombinant bST enabled large-scale applications in farms, enhancing significantly milk production. While it is banned in the European Union (EU), several countries permit the trade and use of recombinant somatotropins in animal husbandry. In this context, effective analytical methods are needed for residue control to avoid an illegal use of rbST but also to prevent fraudulent labeling in some cases. The present review includes studies published in the last 5 years (from 2012 to 2017) to monitor rbST in bovine animals, using liquid-based applications. It is then intended to serve as a practical guide to help those laboratories interested in developing analytical methods to detect rbST use and abuse PB Taylor and Francis Group SN 1082-6076 YR 2017 FD 2017-05-19 LK http://hdl.handle.net/10347/16238 UL http://hdl.handle.net/10347/16238 LA eng NO Regal, P., Lamas, A., Fente, C.A., Franco, C.M., Cepeda, A.
