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).
