Thermo Scientific™ Kit di sintesi di cDNA a singolo filamento Maxima H Minus

Descrizione

Thermo Scientific Maxima H Minus First Strand cDNA Synthesis Kit, available with or without dsDNase, is a complete system for highly efficient synthesis of first strand cDNA. The kit uses the Maxima H Minus Reverse Transcriptase (RT), which is an advanced enzyme derived by in vitro evolution of MMLV RT. The enzyme features the highest thermostability among the derivatives of MMLV RT and lacks RNase H activity.

This kit allows synthesis of long cDNAs up to 20 kb at elevated temperatures (up to 65°C), superseding other systems' abilities to produce full-length cDNA. Due to increased synthesis rates the reaction can be completed in 30 minutes.

For reverse transcription the kit uses Maxima H Minus Reverse Transcriptase (RT), which is an advanced enzyme derived by in vitro evolution of MMLV RT.

The Maxima H Minus First Strand cDNA Synthesis Kit with dsDNase provides a dramatically simplified workflow that combines genomic DNA elimination and cDNA synthesis into one-tube procedure. The kit contains a novel double-strand-specific DNase (dsDNase) engineered to remove contaminating genomic DNA from RNA preps in two minutes without damage to quality or quantity of RNA. Highly specific dsDNase activity towards double-stranded DNA ensures that single-stranded DNA (such as cDNA and primers) is not cleaved, and dsDNase treated RNA can be directly added to reverse transcription.

Features of the Maxima H Minus First Strand cDNA Synthesis Kit include:

• Increased reaction temperatures—the first strand of cDNA can be synthesized within the 42–65°C temperature range
• High yields of full-length first strand cDNA—with RNA templates up to 20 kb
• Flexible priming—oligo(dT)₁₈, random hexamer or gene-specific primers
• Integrated genomic DNA removal step with dsDNase kit

Applications

• First Strand cDNA synthesis for RT-PCR
• Construction of cDNA libraries
• Generation of probes for hybridization
• Antisense RNA synthesis

Additional information about reaction components

• Maxima H Minus Enzyme Mix contains Maxima H Minus Reverse Transcriptase and RiboLock RNase Inhibitor. RiboLock RNase Inhibitor effectively protects RNA templates from degradation by RNases A, B, and C at temperatures up to 55°C.
• Oligo(dT)₁₈ and random hexamer primers are supplied with the kit. Random hexamer primers bind non-specifically and are used to synthesize cDNA from all RNAs in a total RNA population. The oligo(dT)18 primer selectively anneals to the 3'-end of poly(A) RNA, synthesizing cDNA only from poly(A) tailed mRNA. Gene-specific primers may also be used with the kit to prime synthesis from a specified sequence.
• 10 mM dNTP Mix is a premixed aqueous solution of dATP, dTTP, dCTP, and dGTP.
• Nuclease-free water is provided for reaction set-up and dilution of sample DNA. The absence of endo-, exodeoxyribonucleases, ribonucleases, and phosphatases has been confirmed by appropriate quality tests.
