In-vivo potency bioassays

The Erythropoietin potency assay determines biological activity of erythropoietin by quantitative reticulocyte counts in flow cytometry (FACS), using GMP-certified execution of a validated method according to European Pharmacopoeia monograph no. 1316. Daily routines and analysis of more than 500 test samples per year assure high quality data. Bioassay extensive experience in research on erythropoietin analogues includes participation in international round-robin testing and contribution to Pharmeuropa publications.

Bioassay can also predict the potency of Follicle Stimulating Hormone (FSH), Luteinising Hormone (LH) and Human Chorionic Gonadotropin (HCG).
