Figure 3. ICAM-1 protein expression is measured by fluorescence intensity of a labeled anti-ICAM-1 antibody.

(R)-albuterol (A) but not S- or (R-,S)-albuterol (B and C) significantly inhibits TNF-α-induced ICAM-1 protein (p<0.005). *indicates significantly different from control and **indicates significantly different from TNF- treatment, as analyzed by paired T-test.
