Tips for sequencing DNA Use clean DNA. The cleanliness of the DNA is the most important factor in the success of automated DNA sequencing. The DNA should be free of proteins, RNA, polysaccharides and genomic DNA. This can best be achieved by using either a commercial plasmid miniprep kit, or by sequencing a PCR amplified fragment.

DNA sequencing provides the most complete characterization of recombinant plasmid DNAs. Using primers targeting the plasmid backbone and/or the insert sequence, the identity and order of nucleotide bases for any given DNA can be determined.
Protocol for DNA sequencing in PCR tubes (modified from the PE ABI BigDye Ready Reaction Termination Mix protocol) 1) Dilute the 10µM stock solution of sequencing primer 1:15 with sterile dH 2 O. Pipette 2µl of the diluted sequencing primer into appropriately labelled, thin-walled PCR tubes.. 2) Pipette 2µl of the BigDye Ready Reaction Termination Mix into each tube.
For optimum results with automated fluorescent sequencing please follow our recommended protocols as listed on this site.Sequence analysis is carried out on our Applied Biosystems 3730 capillary instruments. The sequencing reactions utilize fluorescently-labelled dideoxynucleotides (Big Dye Terminators) and Taq FS DNA
DNA sequencing was first introduced in 1977, and next-generation sequencing technologies have been available only during the past decade, but the diverse experiments and corresponding analyses ...
Sanger sequencing is a method of DNA sequencing first commercialized by Applied Biosystems, based on the selective incorporation of chain-terminating dideoxynucleotides by DNA polymerase during in vitro DNA replication. Developed by Frederick Sanger and colleagues in 1977, it was the most widely used sequencing method for approximately 40 years.
templates and bacterial genomic DNA can be submitted (please refer to AB Sequencing Chemistry Guide for protocols regarding these large templates). AGRF accepts samples that have been precipitated in either tubes or plates.
Nanopore sequencing with Oxford Nanopore Technologies (ONT) systems enables high-throughput long-read sequencing of both DNA and RNA samples. For high molecular weight DNA (HMW-DNA) samples, read lengths of several hundred kb can be reached with ultra-long-read protocols.The Nanopore sequencing data greatly enable de novo genome assemblies and structural genomic variant and transcriptome studies.
RNA-seq (RNA-sequencing) is a technique that can examine the quantity and sequences of RNA in a sample using next generation sequencing (NGS). It analyzes the transcriptome of gene expression patterns encoded within our RNA. Here, we look at why RNA-seq is useful, how the technique works, and the basic protocol which is commonly used today 1.
