In vitro bioactivity of ELP-sTNFRII (♦) against TNFα-mediated L929 cytotoxicity has an IC50 of 1200 ± 500 nM. This is significantly reduced (p < 0.01) compared with commercial sTNFRII () with an IC50 of 12 ± 4 nM. Coefficients of determination, r2, for fitting to a dose-response curve (Equation 2) ranged from 0.94 to 0.99.
