Figure Lengend Snippet: ACK2 antibody clearance from circulation and depletion of BM HSPCs. (A) Experimental design: C57BL/6 mice were injected i.p. with PBS or 500 μg of purified ACK2 antibody and peripheral blood was collected at days 3, 4, and 5 post-injection for the detection of ACK2 antibody in serum. Representative dot plots showing competition of serum-ACK2 with fluorescently labeled anti-c-Kit clone ACK2 for binding to Lin – c-Kit + BM cells, and corresponding boxplots showing median cell percentages and IQR with whiskers representing the lowest and highest values. (B) Experimental design: C57BL/6 mice were injected i.p. with PBS or 500 μg of purified ACK2 antibody and BM was collected at days 3, 4, and 5 post-injection for the detection of BM HSPCs. Representative dot plots showing Lin – c-Kit + cells labeled with anti-c-Kit clones 2B8 or 3C11 in PBS- and ACK2-injected mice, with boxplots showing median cell percentages and IQR with whiskers representing the lowest and highest values. Statistical significance was determined by non-parametric Kruskal-Wallis test with Dunn’s post hoc multiple comparisons (* P < 0.05; ** P < 0.01; *** P < 0.001). Dot plots shown are representative of individual samples. Data is a pool of two independent experiments from two independent ACK2 production batches. n = 3–8 mice per condition.
