PBMC were grown in the absence or presence of phytohemagglutinin (PHA) for 2 days. TPA was measured in 4-fold diluted cell culture supernatants of unstimulated and PHA stimulated PBMC. Measured values were interpolated from the TPA Standard Curve diluted in Sample Diluent NS and DF corrected. Mean +/-SD, n=2, are graphed.

Serum from 10 apparently healthy male donors was measured in duplicate. The mean TPA concentration was determined to be 2,741 pg/mL with a range of 1,836- 4,012 pg/mL in male donors.

The concentrations of TPA were measured in duplicate and interpolated from the TPA standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean TPA concentration was determined to be 4,710 pg/mL in serum and 4,270 pg/mL in plasma (heparin).
