Proposed protocol for DNA synthesis utilizing the scheme
This unit augments the detailed instructions provided by the manufacturersof oligonucleotide synthesizers.
Syringe method for stepwise chemical synthesis of oligonucleotides.
The PrimeScript First Strand cDNA Synthesis Kit contains all of the reagents necessary for synthesis of first-strand cDNA from total or poly(A)+ RNA using PrimeScript Reverse Transcriptase. Choose this cDNA synthesis kit when you want to synthesize full-length cDNA with provided primers (select from oligo dT or random 6-mer primers, both included in the kit.) This cDNA synthesis kit is powered by PrimeScript Reverse Transcriptase, which has exceptionally strong strand displacement activity and efficiently synthesizes cDNA. PrimeScript RTase is robust, versatile and well-suited for applications requiring full-length cDNA such as cDNA library construction. This PrimeScript-based cDNA synthesis kit also works well with other cDNA-dependent techniques including RT-PCR, cDNA probe preparation and real-time quantitative RT-PCR (qRT-PCR or RT-qPCR). The PrimeScript First Strand cDNA Synthesis Kit is ideal for reverse transcription of many different RNA templates, including GC-rich templates and RNAs with high levels of secondary structure.
In a standardsynthesis cycle, the nucleotide chain grows from an initial protected nucleosidederiviatized via its terminal 3' hydroxyl to a solid support.

The lines cannot be rinsed of whatever reagent theylast contained; thus, determine whether to continue with the synthesisbased on the reactivity of the last reagent in the lines.
It is importantthat the lines be rinsed after an empty reservoir has been detected (somemachines perform this step automatically); otherwise, the oligonucleotideshould be resynthesized.

As is true for all RNA work, equipmentand reagents that will contact unprotected oligonucleotides should be RNasefree () to avoid degradation ofthe synthesized material.
Long oligo synthesis, up to 250 mer; ..
It has been recommended that oligonucleotides up to 50 basesin length should be synthesized on CPG with ~500 angstrom pores, whilelonger oligonucleotides should be synthesized on CPG with ~1000 or largerangstrom pores.

For the casual user of RNA, it is often easierto just purchase small quantities of the required sequence from a ribo-oligonucleotidesynthesis company such as Baron Consulting, Dharmacon Research, Genosys,or Peninsula Labs.
Oligo Synthesis (Primers & Probes) ..
Also, very long synthetic oligonucleotides(300-600 bases) have also been synthesized directly, and inspite of incredelylow yields, rare full length products have been successfully amplifiedby PCR (Ciccarelli, R.

TdT has already been utilized in genomics. It has been used for the production of synthetic homo and heteropolymers (Bollum ), homopolymeric tailing of linear duplex DNA (Deng and Wu ; Eschenfeldt et al. ), oligodeoxyribonucleotide and DNA labeling (Deng and Wu ; Tu and Cohen ; Vincent et al. ; Kumar et al. ; Igloi and Schiefermayr ), rapid amplification of cDNA ends (Frohman et al. ) and in situ localization of apoptosis (Gorczyca et al. ). Scheele and Fukuoka (, ) used TdT to add homopolymeric oligo dC tract to 3′ end of ss linear DNA in order to facilitate synthesis of ds linear DNA using oligo dG primer. However, no attempt to use TdT to synthesize a defined DNA sequence has been reported. Perhaps the random sequence generation by TdT in an uncontrolled system has prevented this.
