We provide the following recombinant proteins and cell lines as a commercial product: 

Some of the proteins are freshly prepared due to their short half-life or special request to our customer’s. Our strict quality control system guarantees that the proteins maintain their full activity upon delivery. In such cases the delivery time is 2-6 weeks after receiving the purchase order.
