Abstract
For the first time the complete cDNA encoding two isoallergens of the non-pyroglyphid dust mite Lepidoglyphus destructor, Lep d 1, allergen has been sequenced. In addition, one of the isoallergens was found to have two variants. Oligonucleotides were designed from known amino acid sequences. The cDNA sequences were obtained by hybridizing these primers to mRNA and enhancement by the RT-PCR technique. To obtain the different complete encoding cDNA sequences and eliminate heteroduplex artifacts, we performed PCR + 1 reactions. Comparison of the amino acid sequence of the allergen shows leader sequences of 16 amino acids for both isoformsKeywords
