Reverse Transcriptase originated from Moloney murine leukemia virus for cDNA synthesis

M-MLV Reverse Transcriptase is one of DNA polymerase  and used for the synthesis of  Single stranded RNA, DNA or complementary DNA strand from RNA:DNA hybrid like AMV RT.
This is also commonly used for cDNA synthesis from RNA but has low endonuclease activity as well as RNase Hactivity comparing to AMV RT


 § Source
 Purified from Moloney murine leukemia virus

 § Unit  Definition
    One unit of the enzyme incorporates 1 nmol dTTP into acid-precipitable material in 10 min at 37℃, using poly(A); oligo dT as a template:primer

 § Quality control
     1) Endonuclease Activity : 1 mg of Type I supercoiled plasmid DNA is incubated with 500   
         units of enzyme in 1x reaction buffer for 1 hr at 37℃. The supercoiled DNA is visualized
         on EtBr-stained agarose gel to verify the absence of nicking or cutting.

     2) Nuclease Activity : 50 ng of radiolabeled DNA or RNA is incubated with 200 units of
         enzyme in 1x reaction buffer for 1 hr at 37℃, resulting ing < 1% release for both DNase

RT/RT- PCR PreMix

HiSenScript™ RH(-) One-Step RT-PCR PreMix Kit 
 RT/RT- PCR PreMix
 Description
        The HiSenScript™ RH(-) One-Step RT-PCR Kit is designed for high sensitive and reproducible detection and analysis of low copies from either a viral RNA or RNA molecules by RT-PCR. Both reverse transcription and PCR are performed in a single tube using target gene specific primer/probe and template RNAs from either total RNA or mRNA. The reaction conditions forHiSenScript™ RH(-) One-Step RT-PCR Kit have been optimized to support a wide range of RT-PCR applications including real-time quantitative procedures. RT-PCR Enzyme mix is a mixture of engineered version of REV (Reticuloendotheliosis virus; REV) reverse transcriptase that reducedRNase H activity and recombinant DNA polymerase complexes with proprietary hot-start specific antibody that inhibits polymerase activity to synthesize DNA from an RNA template. HiSenScript™ RH(-) Reverse Transcriptase can synthesize cDNA at a temperature range of 40–50°C, providing increased specificity, more full-length product than other reverse transcriptase. i-StarMAX™ GH DNA polymerase activity is restored after the denaturation step in PCR cycling at 94°C, providing an automatic “hot start” in PCR for increased sensitivity, specificity, and yield. The 2X RT-PCR Reaction Solution included in consists of a proprietary buffer system that has been optimized for reverse transcription and PCR, Mg2+, dNTPs, tracking dye and stabilizers. The convenient 2X format allows you to add template and primer at any desired concentration.

PCR PreMix

Maxime™ PCR PreMix Kit (i-StarTaq™ GH) 
 Maxime™ PCR PreMix Kit (i-StarTaq™ GH)
Description
Hot start PCR is commonly used to enhance the specificity and sensitivity of PCR. Hot start PCR
technique was developed as a method to minimize the deleterious effects of mispriming at lower
temperatures during PCR. In a PCR reaction, even short incubations at temperatures below the
optimum annealing temperature for a particular set of primers can result in mispriming, elongation
and the subsequent formation of spurious bands.
However, manual hot start PCR is inconvenient, time-consuming, and incurs a risk of cross
contamination.
 Maxime PCR PreMix Kit(i-StarTaq™GH) is the product what is mixed every component:
i-StarTaq™GH DNA Polymerase, dNTP mixture, reaction buffer, and so all-in-one tube for
rxn of PCR. This is the product that can get the best result with the most convenience system.
The first reason is that it has every components for PCR, so we can do PCR just add a template DNA,
primer set, and D.W.. The second reason is that it has gel loading buffer to do electorphoresis, so we
can do gel loading without any treatment. In addition, each batches are checked by a thorough QC.,
so its reappearance is high. It is suitable for various sample’s experience by fast and simple using
method.
Maxime PCR PreMix Kit(i-StarTaq™GH) using i-StarTaq™GH DNA Polymerase, it has been proven to
prevent generation of nonspecific amplification products and primer-dimer artifacts that means
more definitive PCR results can often be obtained in cases where generation of nonspecific
amplification products is a problem, has convenience as well as high specificity and guarantees the
reliable result and the reproducibility for various samples.
