  1. Data on hIR affinity are mean ± s.d. of three independent experiments. Data on lipogenesis are mean ± s.d. of seven independent experiments for NNC2215 and five independent experiments for insulin degludec.
  2. aDetermined from the half-maximal inhibitory concentration (IC50) in the presence of 0, 3, 5, 10 or 20 mM d-glucose or 20 mM l-glucose (with 1.5% human serum albumin).
