Figure Lengend Snippet: Counterregulation of cAMP effectors by PGE2 and LTs. (A). AMs were preincubated with PGE2 (100 nM), LTB4 (10 nM), LTD4 (100 nM), PGE2 plus LTB4, PGE2 plus LTD4 or vehicle control for 15 min, lysed, and assayed for GTP-bound Rap1 as described in “Materials and Methods”. Densitometric analysis was performed for each western blot as described in “Materials and Methods.” (B). AMs were stimulated with PGE2 (100 nM), LTB4 (10 nM), LTD4,(100 nM), PGE2 plus LTB4, PGE2 plus LTD4 or vehicle control for 15 min, after which the proteins were serparated by SDS-PAGE and then the membranes were probed for pVASP (1:500). Subsequently, the membrane was stripped and probed for β-actin (1:1,000). Relative phosphorylation was determined by densitometric analysis of immunoblots from three different experiments and expressed as percentage of control. *, p<0.001 versus control; §, p<0.001 versus PGE2.

Article Snippet: Samples were submitted to SDS-PAGE and the membranes were probed with polyclonal rabbit anti-Rap1 antibody (1:500; Upstate Biotechnology) and bands detected as described in the following section.
