Figure 3From: Standardized method for solubility and storage of capsaicin-based solutions for cough inductionStability of the UV absorbance measurements (λ = 281 nm) of 200 μM CAP solutions prepared in 10% EtOH, as a function of time, for four different storage environments: -20°C (dark), 3°C (dark), 23°C (dark), 23°C (light). Error bars correspond to ± 1 standard deviation.Back to article page
