Figure 7: NO production by A. pinnata in response to addition of nitrite followed by polyamines. Confluent A. pinnata in 20 mL of 10 mM phosphate buffer at pH 7.0 in a 10 cm diameter petridish was supplemented with 0.1 mM nitrite at 10 min followed by addition of 400 μL of dH2O (a), Put (b), Spd (c), and Spm (d) at 20 and 25 min. The arrows mark the additions of distilled water and polyamines.
