IRp60 does not influence eotaxin-induced calcium influx. Eosinophils previously incubated with either anti-IRp60 or control antibodies (isotype, anti-p58.2) followed by the cross-linker sheep anti-mouse F(ab′)2 were washed and loaded with Calcium Green-1AM. The cells were allowed to flow freely in the cytometer until the indicated time point at which eotaxin (1-100 ng/mL) was added (↑). [Ca2+] is expressed as mean fluorescent intensity (MFI). NA indicates not activated; Etx, eotaxin activated (n = 3). Data are expressed as relative cell count ± SD and are representative of 1 of 4 experiments.
