Selecting a Host System for Protein Expression & Production
When selecting a host system for expressing protein there are various considerations. From post translational modifications, equipment available to how quickly you need it, we have mapped out the hosts to help you make the choice. For each host system we have a information that provides you with all our applicable products along the we offer, allowing you to make the right choice based on your needs and budget.
