Description

Description générale

The First Strand cDNA Synthesis Kit is used for the synthesis of the first strand cDNA as the starting reaction for two-step RT PCR.The kit includes Reverse Transcriptase AMV for first strand synthesis, two different primers, our PCR Nucleotide Mix, and Control Neo pa RNA. PCR products that are generated by RT-PCR can be cloned using standard procedures.

The amplification of RNA requires the conversion of the RNA substrate into DNA. This is achieved through the use of a reverse transcriptase such as AMV RT (avian myeloblastis virus reverse transcriptase) or M-MuLV RT (moloney murine leukemia virus reverse transcriptase). The resulting cDNA can be used as a template for a standard PCR.
AMV RT synthesizes the new cDNA strand at site(s) determined by the type of the primer used:

• at the 3′-end of the poly(A) mRNA when Oligo-p(dT)₁₅is used as a primer,
• at nonspecific points along the mRNA template when using the random primer p(dN)₆, or
• at a site determined by a sequence-specific primer.

The use of AMV RT for first-strand cDNA synthesis has certain advantages. The higher thermostability of this enzyme compared to M-MuLV RT allows the reaction to be performed at +42°C, giving higher specificity and better resolution of secondary structures compared to a reaction performed at +37°C.

Spécificité

Heat inactivation: 5 min, 95 °C
Reverse Transcriptase AMV

Application

The First Strand cDNA Synthesis Kit for RT-PCR (AMV) is suitable for:

• Detection of the presence or absence of RNA viruses or other RNA-containing microorganisms (in combination with PCR)
• Quantification of mRNA for monitoring differential expression of a specific mRNA
• First step in the "differential display of mRNA"
• Generation of cDNA libraries with large and full-length inserts
• Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) for reverse transcription of RNA into complementary DNA.

Caractéristiques et avantages

Robustness:

• Transcribes total RNA, mRNA and viral RNA along with difficult-to-transcribe secondary RNA structures
• Obtain cDNA transcripts up to 12 kb
• Higher thermostability (up to 50°C) and specificity than M-MuLV Reverse Transcriptase
• Purification of the resulting cDNA before PCR reaction is not necessary

Flexibility:
It can be used with either sequence-specific primers, poly(dT)15 primers, or random primers, p(dN)6

Conditionnement

1 kit containing 10 components.

Qualité

In the standard cDNA synthesis assay, at least 300 ng of cDNA is synthesized (i.e., 30% yield) when 1.0 μg Neo pa RNA template is incubated with 20 μCi [α-³²P]-dCTP (specific activity of 3000 Ci/mmol) for 60 minutes at +42°C.
