Figure Lengend Snippet: (A) Lamellocytes were bled from at least 24 control ( w 1118 ), homozygous Rac1 J11 , and homozygous Rac2 Δ larvae approximately 40 hours post-parasitization and stained for Myospheroid protein expression (red), as well as actin (green). (B) Anti-Mys antibody was bound to the surface of lamellocytes bled from control ( w 1118 ) larvae, followed by internalization for various times as indicated (n = 12 larvae/time-point). The cells were not permeabilized (C) Graph indicating percentage of surface Myospheroid expressed on control ( w 1118 ) haemocytes. Fluorescent intensity was measured using ImageJ to calculate the amount of cell surface Myospheroid on lamellocytes. Asterisk indicates significant difference (One-way Anova, P <0.01), errors bars indicate ± SE; n = 12 larvae/time-point, 0 minutes n = 1256 haemocytes, 30 minutes n = 1294, 60 minutes n = 1175). (D) Anti-Mys antibody was bound to the surface of lamellocytes bled from control ( w 1118 ) larvae, followed by internalization for 120 minutes as indicated (n = 12 larvae/time-point). Cells were permeabilized to allow for visualization of internalized Myospheroid. Size bars always indicate 20 µm.
Article Snippet: Mouse monoclonal anti-Myospheroid (Developmental Studies Hybridoma Bank, Iowa, USA), lamellocyte-specific mouse monoclonal antibody (L1a) and plasmatocyte-specific monoclonal mouse anti-Nimrod , were all used undiluted, mouse monoclonal anti-Rac1 (BD Biosciences) diluted 1∶250, mouse monoclonal antibody anti-α-Tubulin (Sigma) diluted 1∶1,000, rabbit polyclonal anti-α-Tubulin (Abcam) diluted 1∶500, rat monoclonal anti-Hsp90 (Abcam) diluted 1∶300.
