Fig. 4From: Eotaxin Triggers Eosmophil-Selective Chemotaxis and Calcium Flux via a Distinct Receptor and Induces Pulmonary Eosinophilia in the Presence of Interleukin 5 in Mice Calcium flux in eosinophils in response to various concentrations of eotaxin Eosinophils were loaded with the calcium sensitive dye fura-2 and their response to different concentrations of eotaxin (indicated with arrows) was assessed in a fluorimeter. The data is expressed as the ratio of emission at 510 nm after excitation at 340 and 380 nm respectively.Back to article page
