• And other applications like virtual Northern Blots or array probe generation


Technology overview

Mint-2 cDNA synthesis kit is based on a novel technology (patent pending) utilizing the specific features of MMLV-based reverse transcriptase (RT). First strand cDNA synthesis starts from the 3´-end CDS adapter containing an oligo(dT) sequence that anneals to poly(A) stretches of RNA. When Mint RT reaches the 5´-end of the mRNA, it adds several non-template nucleotides, primarily deoxycytidines, to the 3´-end of the newly synthesized first-strand cDNA (Schmidt and Mueller, 1999). This oligo(dC) stretch base pairs to complementary oligo(dG) sequence located at the 3´-end of a special deoxyribooligonucleotide adaptor, called PlugOligo. Mint RT identifies PlugOligo as an extra part of the RNA-template and continues first strand cDNA synthesis to the end of the oligonucleotide, thus incorporating PlugOligo sequence into the 5´-end of cDNA.
The last 3´-dG residue of the PlugOligo is a terminator nucleotide containing a 3´-phosphate group. This blocking group prevents unwanted extension of the PlugOligo. Under standard conditions Mint RT can hardly use PlugOligo as a template; however, a specially tailored IP-solution (solution for incorporation of PlugOligo sequence) dramatically increases the efficiency of this process.
At the final step, ds cDNA is amplified by PCR. Use of Encyclo polymerase (see link below) and specially designed primers allows synthesis of full-length-enriched cDNA that is flanked by PlugOligo and CDS adapter sequences.


Applicable to all eukaryotic organisms and all tissue sources

Compatible with TRIMMER cDNA normalization kit

cDNA prepared with the MINT-2 kit can be normalized using TRIMMER Kit (Cat# NK001-EV)- see link below- to decrease the prevalence of high abundant transcripts.

Product Use Limitations: MINT Kit is intended for research purposes only.

Endnotes: PCR is the subject of patents issued in certain countries. The purchase of this kit does not include a license to perform PCR. However, many researchers may not be required to obtain a license. Other investigators may already have a license to perform PCR through use of a thermal cycler with the appropriate label license.
