Novel transcription reaction conditions and Ambion's patented, high-yield technology allow the synthesis of 10–50 times the amount of RNA produced詳細を見る
Novel transcription reaction conditions and Ambion's patented, high-yield technology allow the synthesis of 10–50 times the amount of RNA produced by conventional transcription reactions. Each Ambion™ kit includes sufficient reagents for 40 reactions.
• Exclusive, ultrahigh yield technology is fast: 2 hour reaction time • Amplifies aRNA for gene array analysis and other applications • Efficiently incorporates many modified nucleotides
A typical 20 μl MEGAscript™ reaction with 1 μg of the pTRI-Xef-1alpha control template will yield over 100 μg of transcript. The versatility of the MEGAscript™ kit allows for manipulation of the reactions to include specialized reagents such as modified nucleotides, cap analog, or additional polymerase.
Accessory Products: MessageAmp™ aRNA Amplification Kits are powered by MEGAscript™ technology and have been developed especially for the amplification of cRNA prior to array analysis. To purify in vitro transcription products from free nucleotides, buffer components, and enzymes, Ambion recommends using the MEGAclear™ Kit (SKU#AM1908) and the MEGAclear™-96 Kit (SKU#AM1909).
I am using the MEGAscript SP6 Transcription Kit for in vitro transcription. I ran my reaction product on a denaturing gel and got a smear. Can you offer some advice?
If the RNA appears degraded (e.g., smeared), remove residual RNase from the DNA template preparation before in vitro transcription. Do this by digesting the DNA prep with proteinase K (100-200 µg/mL) in the presence of 0.5% SDS for 30 min at 50°C, and follow this with phenol/chloroform extraction. The RNase Inhibitor that is present in the transcription reaction can only inactivate trace RNase contamination. Large amounts of RNase contamination will compromise the size and amount of transcription products.
