ALK and amyloidoma: Neutrophil depletion, accomplished using the anti-Ly6G (1A8) antibody and confirmed by flow cytometry and histological analysis (Supplementary Figure 3), significantly delayed ALκ(TAL) amyloidoma clearance in NU/NU mice as evidenced by changes in DL800 fluorescence intensity over 18 days post amyloid injection (Figures 7A, B).
