Toolbox in the Menu Bar | Molecular Biology Tools () | Cloning and Restriction Sites ()| Gateway Cloning () | Create Expression Clone ()
This will open a dialog where you can select on or more entry clones (see how to create an entry clone). If you wish to perform separate LR reactions with multiple entry clones, you should run the Create Expression Clone in batch mode.
When you have selected your entry clone(s), click Next.
This will display the dialog shown in figure 19.24.
Clicking the Browse () button opens a dialog where you can select a destination vector. You can download donor vectors from Invitrogen's web site: http://tools.invitrogen.com/downloads/Gateway%20vectors.ma4 and import into the CLC Genomics Workbench. Note that the Workbench looks for the specific sequences of the attR sites in the sequences that you select in this dialog (see how to change the definition of sites in Technical information about modifying Gateway cloning sites). Note that the CLC Genomics Workbench only checks that valid attR sites are found - it does not check that they correspond to the attL sites of the selected fragments at this step. If the right combination of attL and attR sites is not found, no entry clones will be produced.
When performing multi-site gateway cloning, the CLC Genomics Workbench will insert the fragments (contained in entry clones) by matching the sites that are compatible. If the sites have been defined correctly, an expression clone containing all the fragments will be created. You can find an explanation of the multi-site gateway system at http://tools.invitrogen.com/downloads/gateway-multisite-seminar.html
Click Next if you wish to adjust how to handle the results. If not, click Finish.
The output is a number of expression clones depending on how many entry clones and destination vectors that you selected. The attL and attR sites have been used for the recombination, and the expression clone is now equipped with attB sites as shown in figure 19.25.
You can choose to create a sequence list with the bi-products as well.
