Are there two vectors for protein expression using QIAgenes in insect or mammalian cells?

No, the same vector can be used to express QIAgenes in both systems, as the optimized DNA sequence leads to enhanced expression in insect and mammalian cells. No subcloning is necessary.

For additional details on the vector, please see the vector map provided in the handbook and on individual datasheets. The vector sequence is downloadable from the QIAGEN web site.
