Effect of fertilization on the distribution of active Src-family PTKs at the animal pole.

Eggs were fixed before (A) and at 30 seconds (B), 1.0minute (C), 2.5minutes (D), and 8 minutes (E) after insemination and the chorion was removed by dissection after protease treatment to ensure complete access for immunostaining. The eggs were immunolabelled with the clone 28 antibody as described in Figure 2. Conditions of illumination and signal amplification in the fluorescence channel were maintained at a constant level to allow comparison of immunofluorescence intensity. Arrows indicate the position of the micropylar region and magnification is indicated by the bar, which represents 100μm.
