Comparison of the Isoelectric Focusing Patterns of Darbepoetin Alfa, Recombinant Human Erythropoietin, and Endogenous Erythropoietin from Human Urine
TL;DR: Although darbepoetin alfa was approved only recently, it was detected in the urine of three athletes competing in the 2002 Winter Olympic Games and showed that pharmacokinetic factors have a greater influence on biological activity than receptor binding affinity.

Detection of recombinant human erythropoietin in urine by isoelectric focusing.
TL;DR: The electropherograms showed that the pattern of bands arising from urinary rHuEPO is different from that of endogenous urinary EPO, and the isoelectric focusing method detects rHu EPO in most urine samples collected 3 days after nine doses of epoetin alfa.
Derivatization of bisphenol A and its analogues with pyridine-3-sulfonyl chloride: multivariate optimization and fragmentation patterns by liquid chromatography/Orbitrap mass spectrometry.
TL;DR: Derivatization of BPA and its structural analogues with pyridine‐3‐sulfonyl chloride is proposed as a specific, sensitive, high‐throughput approach to their analysis by liquid chromatography coupled to electrospray ionization mass spectrometry.

Assignment of a Reference Value of Total Cow’s Milk Protein Content in Baked Cookies Used in an Interlaboratory Comparison
TL;DR: In this paper , isotope dilution mass spectrometry (IDMS) was used to assign a reference value of the total cow's milk protein (TCMP) content in a baked cookie and its associated uncertainty.
