FIGURE 9. Electrospray ionization mass spectrometric analyses of glycerophosphocholine lipids from peritoneal macrophages of wild-type and iPLA2β-null mice.

FIGURE 9

Phospholipids from wild-type (A and C) or iPLA2β-null (B and D) macrophages were analyzed as Li+ adducts by positive ion ESI/MS, and relative abundances of ion currents plotted versus m/z value. A and B represent total ion current, and C and D represent ESI/MS/MS scans for constant neutral loss of 183.
