Figure 4 PCBAT with cat allergen extracts on cat allergic subjects validated with inhalant allergen challenge
PCBAT using cat allergen extracts from HollisterStier (dilution factor 1:250; 1:1,250; 1:6,250; 1:31,250; 1:156,250 and 1:781,250) were performed on (A) 17 clinal reactivity validated cat allergic subjects; (B) Scatter plot showed the relationship between the PCBAT AUC from the allergic groups and the corresponding natural log transformed dosage response slope. (C) PCBAT using cat allergen extracts were also performed on 6 atopic but non-cat sensitized subjects, spearman test and R square was calculated and p<0.05 were considered significant.
