The anti-rHuEPO SOMAmers bind specifically to rHuEPO and are sensitive to the conformation of the protein. (a) Comparision of binding affinity (KD) of SOMAmers to recombinant human and murine erythropoietins (rHuEPO and rMuEPO respectively) as measured by BLI. (b,c) BLI sensorgram traces for Epogen/Procrit association and dissociation to SOMAmers SL5003 (b) and SL5004 (c). For thermal stability studies, SOMAmer:rHuEPO binding was measured following incubation of Epogen/Procrit at 60 °C for 0 h (red), 1 h (green) or 17 h (blue).
