Summary: This collection contains the protocols and recipes for the preparation of cell-free RNAPT7 transcription/translation coupled reactions.The crude extracts are obtained from IPTG-treated E.coli BL21 DE3 STAR cells. IPTG triggers RNAPT7 expression and accumulation in cells before collection. Reactions take place when the cell extract is mixed with a maltodextrin-based energy solution along with amino acids solution and other salts (Magnesium and Potassium). This system allows transcription/translation coupled reactions from plasmid DNA that contains T7 promoter transcriptional units. In our hands, it has been possible to express different fluorescent reporters, including deGFP which is highly efficient. Products of the reaction can be measured during the whole reaction time in a plate reader with appropriate optic filters, open hardware cameras, and microscopes. When set up correctlly, deGFP fluorescence intensity is detected as fast as ∼30 minutes after the reaction starts and it shows a rapid increase during the first ∼2.5-3.0 hours. The system presented here contains the features highlighted bellow, and is an adaptation of protocols and findings from the following listed papers:
1.- This system uses maltodextrin and Polyphosphate-based energy solution:

Can't find your Protocol?
We recommend that you click next to the search bar to check some helpful tips on searches and refine your search firstly. If you want to find a specific protocol and you know the DOI of the protocol already, it's easier to enter a DOI to search. You can refine the search results using Facets on the left side of the search results page. If you are on the table view, you can also search in a specific column by clicking the column title and enter the keywords.
If you still could not find your protocol in the search results, please help us by adding it into the system — it's easy. Create and publish your protocols at Protocols.io.
