The Retic Lysate IVT™ Kit efficiently translates in vitro-synthesized transcripts, poly(A) RNA, and total RNA, including difficult-to-translate RNAs. The optimized lysate results in high protein yield, biological activity, and consistent performance. Advantages of the Retic Lysate IVT™ Kit:

• Efficiently translates a wide variety of high molecular weight proteins and both capped and uncapped mRNAs
• Accommodates large volume of template mRNA

How it works
The lysate has been optimized for translation by the addition of an ATP-regenerating system, hemin, and calf liver tRNA. Included in the kit is an optimized Translation Mix (-Met or -Leu) for the translation of both capped and uncapped messages along with High and Low Salt buffers. These buffers can be used to maximize protein yield and activity from difficult-to-translate sequences. A report in Nucleic Acids Research (1) found that some commercial reticulocyte lysates had poor fidelity for initiation at the appropriate AUG initiator codon. The Retic Lysate IVT™ Kit was tested using Kozak's constructs and it demonstrated high fidelity for initiating at the proper AUG.
