Figure 1From: A streamlined implementation of the glutamine synthetase-based protein expression systemThe principal vectors used in this study. The three panels show the vector designs for the IRES (A), dual promoter (B) and T2A (C) versions of FcERα-eGFP-GS-pOPINEE12G (not drawn to scale). The vectors are 9491, 10697 and 8953 base pairs in size, respectively.Back to article page
