Figure 6. Expanded view of HPLC chromatograms of extracts and a standard around the cADPR peak.
The standard (dotted line) contained nominally 16 μM cADPR. The two almost identical chromatograms were from two extracts from cells from one donor. One extract was from cells stimulated with fMLP (1 μM for 2 min; black) and the other one was from unstimulated cells (grey).
