||Abstract: "To address the need for rapid and robust assays, [investigators] designed a microfluidic device that measures neutrophil chemotaxis directly from a single droplet of blood. [They] validated the assay by comparing neutrophil chemotaxis from finger prick, venous blood and purified neutrophil samples. [They] found consistent average velocity of (19 ± 6 μm/min) and directionality (91.1%) between the three sources."
||P.5 bottom paragraph: "Neutrophil velocity from finger prick whole blood was comparable for both fMLP (N-Formylmethionyl-leucyl-phenylalanine, 19 ± 6 μm/min) and LTB4 (Leukotriene B4, 20 ± 7 μm/min) (Fig. 4b)."
