Synthesis of biologically active recombinant Der f II.
A cDNA library corresponding to mite protein was screened employing anti-Der f II antibody. Two possible clones containing plasmids pFL1 and pFL11 were obtained. The two plasmids had insertions of about 500 basepairs. The DNA sequences of the two insertions were determined, from which the amino acid sequences were deduced. The amino acid sequence of the purified native Der f II protein could be determined to 45 residues from the N terminus. As a result of comparison, we concluded that the cDNAs prepared from live Dermatophagoides farinae mite corresponded to the mite allergen Der f II. The recombinant Der f II was biologically active.
