Immunohistochemistry, immunofluorescence and flow cytometry analysis of the localization of CgDM9CP-4 protein. (A) Distribution of CgDM9CP-4 was visualized by Alexa Fluor 488-labeled goat-anti-rat antibody (upper panel), the rat pre-immuned serum was used as control (lower panel), the tissues were stained with Evans blue dye (red). Bar= 50 μm. (B) Expression of CgDM9CP-4 on the membrane of hemocytes as detected by flow cytometry. (C) Localization of CgDM9CP-4 in hemocytes. Nucleus was stained with DAPI (blue), CgDM9CP-4 (green) and the cell membrane were stained with CM-DIL (red). Bar= 10 μm. (D) Distinct gating by forward scatter (FSC) and Alexa Fluor 488-labeling and (left), contour by FSC and Alexa Fluor 488-labeling showing the specific group of CgDM9CP-4-positive hemocytes (middle), size and granularity of CgDM9CP-4-positive hemocytes were analyzed by Side scatter (SSC) and FSC (right).
