Figure 3. G–V corrections for intrinsic outward rectification in the absence of internal polyamines .

G–V relationships in the absence (white symbols) or presence (black symbols) of internal polyamines were plotted. The corrected G–V relationships (cyan symbols) were obtained by dividing the value of the spermine G–V by the non‐spermine G–V (G _corr = G _Spm/G _noSpm). Note the importance of performing this correction for each receptor type, as the intrinsic outward rectification properties differ.
