A concentration-response curve for S-nitrosoglutathione (GSNO) in incubated rat Leydig cells. Purified rat Leydig cells were prepared as described in “Materials and Methods” and incubated in the presence of luteinizing hormone (LH) (0.5 ng/mL) and various concentrations of freshly prepared GSNO. Results are presented as in Figure 1 and are a representative experiment repeated 3 times with similar results.
