Localization of Gurken Protein in Egg Chambers of Wild type and sec61βP1 Germline Clones during earlier stages of Oogenesis. Drosophila egg chambers of the indicated genotype, wild type, (WT) or egg chambers mutant for sec61β, (sec61β), stained for actin using labelled Phalloidin (blue) and Gurken (red). A -B) Staining for Gurken protein (A) in the stage 6 oocyte from wild type, co-staining with actin (B) to delineate the follicle cells. C-D) Staining for Gurken protein (C) in sec61β mutant oocytes shows protein distributed all over the oocyte, co-staining with actin to delineate the follicle cells. f, indicates the follicle cells, o, the oocyte and n, the oocyte nucleus.
