Figure Lengend Snippet: (A) Purified and rested neutrophils from healthy donors (H) and SCD patients in steady state (SS) were left untreated in RPMI as control or treated with 20 μM hemin. Median Fluorescence Intensity of F-Actin (upper panel) and CD63 (lower panel) in F-Actin/CD63 double positive neutrophils with normal multi-lobulated nuclei is shown. (Healthy N = 7; SCD N = 6). (B) Z-stack stills of SCD neutrophils left in RPMI for 30 minutes showing neutrophils with roughed cell membranes (yellow arrows, upper panel). Staining for DNA (blue), F-Actin (green) and CD63 (red) is presented (lower panel). (C) MPO release was assayed by ELISA following 30 minutes incubation with or without the hemin stimulus (H (Healthy) N = 4; SS (SCD) N = 4). Degranulation response was assayed in terms of MPO ng/ml plasma (upper panel), or fold increase over healthy neutrophils (lower panel). Data presented as dot plots±S.D., significance calculated with an unpaired Mann-Whitney test.

Article Snippet: The supernatants were then assayed with a Human Myeloperoxidase Quantikine ELISA Kit from R&D Systems according to the manufacturer’s instruction.

Figure Lengend Snippet: Figure 4. Antioxidative enzyme activity in the two genotypes. (A). Ascorbate peroxidase (APX) activity in LT and LS, in all three time points (24 h, 72 h, 7 d). APX activity is shown as APX units/mg of protein. (B). Peroxidase (POD) activity in LT and LS, in all three time points (24 h, 72 h, 7 d). POD activity is shown as POD units/mg of protein. Control samples are shown in orange, and treatment samples are shown in blue. The significance of the difference between the control and treatment of each parameter was determined by t-test and is shown as ** (p < 0.01), * (p < 0.05), and NS (statistically not significant at p > 0.05).

Article Snippet: In alignment with the manufacturer’s instructions, the peroxidase (POD) Activity Assay Kit (Elabscience®, Wuhan, China) was employed for this purpose.
