Figure 5From: Glutaraldehyde-Modified Recombinant Fel d 1: A Hypoallergen With Negligible Biological Activity but Retained ImmunogenicityImmunologic characterization of modified rFel d 1. A, ImmunoCAP inhibition. ImmunoCAP inhibition was performed with a cat epithileum and dander CAP (e1) and a serum pool of >100 cat-allergic patients. B, Stripped basophil histamine release assay. C, Competitive RIA. D, Fel d 1-specific sandwich ELISA. E, IgG RAST. Symbols used: nFel d 1 (○), rFel d 1(●), and rFel d 1-mod (■).Back to article page
