There appears to be some particular advantages to daf compared to the more traditional PCR approach.

DNA amplification fingerprinting: Another diagnostic tool?

Until then it would seem reasonable to predict that daf ampification will provide high versatility while retaining the selectivity and sensitivity of long, ampoification primer PCR and will shortly be part of the diagnostic trade of clinical microbiologists.

The conditions required for effective long dat, dual primer PCR are considerably more stringent with respect to hybridization and enzymatic conditions than for daf.

Please review our privacy policy. The polymerase chain reaction: Particularly important are the specialized silver staining method 8 required for resolution of small, as opposed to large, amplicons, and the primer concentrations required for effective priming. Application of the polymerase chain reaction to the diagnosis of human genetic disease. The high sensitivity and specificity of properly targeted long chain primer pairs and the great variety of specimens amenable to PCR analysis, including nonculturable specimens such as amplificafion embedded tissues, has generated numerous diagnostic applications 4.

The polymerase chain reaction.

Multiple priming sites on each Ena strand are amplified efficiently by short primers under relaxed conditions and the number of amplicons reproducibly obtained in daf is largely dependent on the short primer sequence rather than length, provided the number exceeds four 5 — 7.

Another genetic approach has recently been suggested by two groups 56 in which PCR amplification of DNA polymorphisms was directed by single small primers only eight to 10 nucleotides in length.
