Figure 6From: An immunoassay that distinguishes real neuromyelitis optica signals from a labeling detected in patients receiving natalizumab Detection of α4 chain integrin in HEK cells by RT-qPCR. Percentage of expression of integrin α4 (ITGα4) was similar in control non-transfected HEK cells (HEK293) or in HEK cells transfected with AQP4 (HEK293M23) or with the empty vector (HEK293p3T). No amplification was observed in the water control sample.Back to article page
