Figure 4. Post-extraction stability of SDs in plasma.

Figure 4

To determine the post-extraction stability of SDs, analyzed samples were kept in 4°C for 24 hours and reinjected. Panel A shows the extracted ion chromatograph of SDs and C17-SO internal standards. Table shows the stability of SD compounds spiked in plasma and as shown, minimal loss is detected at 24 hrs.
