| The supernatant was assayed for the determination of glycerol as just described for triglycerides. |
| Transcription rates were assayed using nuclear run-on analyses as previously described. |
| Nitric oxide and nitrogen dioxide were chemically assayed as nitrite from sorbent tubes by using spectrophotometry. |
| Nodules were extracted and assayed for starch, sucrose, glucose, fructose, total amino acids, and ureides as described previously. |
| Luc activity was assayed quantitatively with a liquid scintillator using the photon-counting mode after the feeding of luciferin as substrate. |
| Pepc was assayed fluorometrically in real time under suboptimum conditions of pH and limiting substrate in a 17 nl droplet. |
