We do cloning from the ORFeome collection, as well as from your own Gateway-compatible PCR products and plasmids to a number of destination vectors. Our selection of vectors includes a wide range of expression vectors ranging from bacterial and vertebrate expression to lentivectors. If your favourite vector is not on our list, feel free to suggest an update to our collection.
Additionally we provide help in designing primers to create Gateway-compatible PCR products from non-Gateway-compatible templates. We can then clone the PCR products to destination vectors in two cloning steps.
The cloned products are delivered as transfection grade minipreps and glycerol stocks. Minipreps can be delivered by mail if necessary.
You can make your cloning order with the same form as the library clone orders.
The following control constructs can be cloned to all destination vectors.
With our site-directed mutagenesis service, we can generate one to a few nucleotide sequence alterations to our library-derived plasmids.
The mutagenesis service fee covers the site-directed mutagenesis reaction (two tries), as well as two miniprep DNA extractions and sequencing of two mutated plasmid clones. An additional fee is charged when competent cells than standard Dh5alpha are needed (e.g. for lentiviral plasmids).
We use a Phusion HF polymerase with an error rate of 4,4 x 10-7, and while random mutations caused by the polymerase are rare, they are still possible. We confirm the mutated site by sequencing, but we do not guarantee that the construct is free of replication errors outside the mutated region.
We primarily do mutagenesis service only for the clones derived from our libraries. If you would like to have your own construct mutated, please contact us, and we will evaluate each service request case-by-case. The map and the full vector sequence are needed for the approved services. Because we can't guarantee the quality of customer's own plasmid we can't guarantee the success of the mutagenesis. We will make two trials but will need to charge them independent of the success. Failed mutagenesis is rare (<10%).
