mAb HTN-Gn1 modestly neutralized live virus in vitro with an IC50 of 15.47 μg/ml, which is within the range of IC50 values observed for anti-hantavirus mAbs obtained from hamsters (with IC50s ranging from 0.25 to 20.97 μg/ml for 19 hamster mAbs) (27) and humans (0.205 μg/ml and 6.60 μg/ml for two human mAbs) (23). This evidence concerns the gene GYG1 and hypertensive disorder.
