Part Descriptions

LP269367-1   CBA IFA
In cell binding assays or cell-based assays (CBA) also known as cell-based immunoassays, the DNA coding for a particular antigen is transfected into cultured cells, which are then used directly as substrate for antibody detection by immunofluorescence. The advantage of CBA IFA over conventional immunoassays is that purification and stability of the antigen is not required and they provide an in vivo substrate. Source: Regenstrief LOINC,

LP411550-9   Glial fibrillary acidic protein.alpha subunit Ab.IgG
Glial fibrillary acidic protein (GFAP) antibody is a biomarker for immune inflammation. GFAP IgG autoantibody binds to GFAPα, and is found in serum and cerebrospinal fluid (CSF) of indiviuals with GFAP astrocytopathy. GFAP antibodies are detectable by immunofluorescence (IF), cell-based assay (CBA) and western blot. GFAP astrocytopathy often overlaps with other autoimmune diseases, making diagnosis challenging due to the coexisting neural autoantibodies. PMID: 30568655 Source: Regenstrief LOINC
