1. Select the appropriate method for vector linearization in the top radio button.

2. Enter the vector sequence according to the linearization method and then select the restriction enzyme cleavage site:

A. If the linearization method is‘Single Restriction Enzyme Digestion’, please enter the complete sequence of the vector or the sequence near cloning site into the first text box. Then select the restriction enzyme from selection list.

B. If the linearization method is‘Double Restriction Enzymes Digestion’, please enter the complete sequence of the vector or the sequence near cloning site into the first text box. Then select the restriction enzymes from the selection lists.

C. If the linearization method is‘PCR Amplification’, please enter the upstream sequence of the vector cloning site into the first text box and the downstream sequence of the vector cloning site into the second text box.

3. Enter the complete sequence of inserts into the bottom text box, and the direction is from 5' to 3'.

4. Click the‘Generate CE II Amplification Primers’button. The complete forward and reverse amplification primers of the insert are showed in the lower text box. Each primer contains a recombinant sequence (lowercase) and a specific amplification sequence (uppercase). If the linearization method of the vector is‘PCR Amplification’, the amplification primers sequence of corresponding vector will be showed in the bottom text box.

5. Click the‘Empty’button to continue designing the CE II cloning primers for other inserts.

Note:

1. If the linearization method is‘Single Restriction Enzyme Digestion’and the cleavage site is not unique, the sequence between the two outermost cleavage sites of the input sequence is excised in the software default.

2. If the linearization method is‘Double Restriction Enzymes Digestion’, the sequence between the two restriction cleavage sites of the input sequence is excised in the software default.

3. If the linearization method is‘PCR Amplification’, the insert will be cloned into the two input sequences in the software default.
