Simultaneous Sequencing of Multiple Polymerase Chain Reaction Products and Combined Polymerase Chain Reaction with Cycle Sequencing in Single Reactions

DNA sequencing with Thermus aquaticus DNA polymerase and direct sequencing of polymerase chain reaction-amplified DNA.

The highly thermostable DNA polymerase from Thermus aquaticus (Taq) is ideal for both manual and automated DNA sequencing because it is fast, highly processive, has little or no 3'-exonuclease activity, and is active over a broad range of temperatures. Sequencing protocols are presented that produce readable extension products greater than 1000 bases having uniform band intensities. A combinati...

18S rDNA polymerase chain reaction and sequencing in onychomycosis diagnostics.

Diagnostic approaches to onychomycosis have traditionally been based on a combination of culture and microscopy. In the present study clinical specimens from 346 patients with suspected onychomycosis were analysed by 18S polymerase chain reaction (detection) followed by sequencing and subsequent database search (identification) in parallel with routine culture on agar (detection and identificat...

Direct single stranded sequencing from agarose of polymerase chain reaction products.

The polymerase chain reaction (PCR) has made possible the rapid isolation and amplification of specific DNA segments, which can then be used for a wide range of applications (1). Direct sequencing of PCR products has been described, using assymetric PCR, which requires purification of the PCR product, or inclusion of 10% DMSO in the sequencing reaction (2, 3, 4). However, these methods of seque...

Automated DNA sequencing methods involving polymerase chain reaction.

Polymerase chain reaction (PCR) as a method for preparing DNA templates has been used for several DNA sequencing applications. An in situ procedure for directly sequencing PCR products by the dideoxy-termination method has been developed by using fluorophore-labeled sequencing primers. Completed sequence reactions were combined and loaded into a single electrophoretic lane of a fluorescence-bas...
