nameAquaporin 4 water channel IgG Ab [Titer] in Cerebral spinal fluid by Cell binding immunofluorescent assay
statusACTIVE

Fully-Specified Name

componentAquaporin 4 water channel Ab.IgG
propertyTitr  =  Dilution Factor (Titer)
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemCSF  =  Cerebral spinal fluid
scaleSemiQn
methodCBA IFA  =  Cell binding assay immunofluorescent assay:  Cell binding assays are performed using cells that are engineered to only express the antigen of interest, which increases their specificity compared to traditional immunofluorescent assays.
