by southern hybridization using a genomic dna fragment carrying a human ige heavy chain constant region gene ( c epsilon ) as a probe , we analyzed the organization of human c epsilon genes and their flanking regions in 23 atopic dermatitis and 6 senile erythroderma patients with elevated serum ige levels , and 6 atopic dermatitis patients with normal ige levels .
