Effect of L-NMMA on Epo protein from Hep3B cells stimulated by hypoxia.
Hep3B cells were incubated with different concentrations of L-NMMA under hypoxic conditions (1% O2) for 24 h. Epo protein was measured by RIA. Four separate experiments were performed (n = 4). Error bars represent 1 SD. *P < .01.
