EGFr in rat e10 placenta : FFPWS using Abcam ab32077

Ratplacenta-A1in1500c

Intense membraneous positivity is seen in a proportion what seem to me to be maternal decidual cells. This pattern is seen in rat/mouse placentas with ab32077, ab40815, ab52894. Placental cells proper are either a moderate positivity or are unstained if further diluted ( however, thos decidual cells are still positive.

Again, anybody know if this is specific/non-specific?
