Figure 7. Effects of surfactant on RBL cell activation by Ova.

(A) Images demonstrating Ca²⁺ release in mast cells, upon addition of serum and Ova. (B) There were no differences in the baseline values of the calcium with and without surfactant (n = 5−6). (C) The peak increase in calcium (n = 5−6) and the (D) subsequent plateau were not significantly attenuated by prior treatment with surfactant (n = 5−6).
