Simultaneous detection of delta F508, G542X, N1303K, G551D, and 1717-1G-->A cystic fibrosis alleles by a multiplex DNA enzyme immunoassay.

We describe the use of a polymerase chain reaction in conjunction with a DNA enzyme immunoassay for the simultaneous detection of five common cystic fibrosis mutations. The method is specific, sensitive, rapid, and proved effective in Guthrie card-based screening of cystic fibrosis mutations.
