Type V: CSF and serum show significant bands. Type IV: Identical bands (not belonging to the basic pattern) in serum and CSV: Negative, no identical synthesis, systemic desease. Type III: CSF shows 2-3 or more (IgG-spec.stain, general stain: 4 or more) supplementary oligoclonal bands in addition to identical bands in both lanes: Positive, intrathekal syn. Type II: CSF shows 2-3 or more (IgG-spec.stain, general stain: 4 or more) supplementary oligoclonal bands (not belonging to the basic pattern): Positive, intrathekal synthesis. The PRDI-BF1-RIZ1 homologous (PR) domain is a newly recognized amino-terminal module 1 and was first noted for the homologous 100amino acid region shared between positive regulatory domain I binding factor 1 (PRDI-BF1) (PRDM1) 2 and retinoblastoma-interacting zinc finger protein (RIZ) (PRDM2). Type I: CSF and serum show no or only 1 additional bands: Negative, no intrathekal synth. We recorded the IgG index both on a continuous scale and binary as normal or elevated. Figure 2 EEG showing generalised slow waving (A) with normalisation after corticoid treatment (B). The presence of OCB was registered binary as positive (2) or negative (01). Figure 1 Isoelectric focusing illustrating oligo-clonal banding in the cerebrospinal uid (CSF) of our patient (right lane) together with CSF-positive (left lane) and serum-negative (middle lane) control. IgG and albumin in serum and CSF were measured with the routine method at the different hospital trusts at the time. Examples: Oligo-IgG Interpretation Examples Serum was collected at the same time as the lumbar puncture. Hemolysate in the IEF-lanes? -> Oligo-IgG Troubles. Oligoclonal bands were present in the CSF of a sample obtained on day 10 after admission. When IgG-selective stainings are applied Albumin, Transferrin and Cystatin will be not visible! Please consider that some proteins are specific for the CSF (Cystatin C, ß-Trace and Transferrin). General: The bands in the IgG-region produced by the cerebrospinal fluid (CSF) and the bands expressed in the serum (S) from the same patient are compared to each other.
