Fig. 1. The effects of laminarin, PMA and zymosan on PKC phosphorylation.
Lymnaea stagnalis haemocytes were challenged with (A) laminarin (10
mg ml-1), (B) PMA (10 µmol l-1) or (C) zymosan (10
µg ml-1) for 0-30 min and their effects on PKC phosphorylation
determined by western blotting. Equal amounts of protein were loaded in each
lane and membranes were probed with anti-phospho PKC (pan), anti-phospho
PKC
, or anti-phospho PKC
ßII antibodies as
indicated in the figure. Anti-actin antibodies were used to confirm equal
loading of proteins. Relative PKC phosphorylation levels (shown in the graph
in A) detected with anti-phospho PKC (pan) antibodies were determined by image
analysis. Values are means ± s.d. from four independent experiments.
