CSF proteins in neurological disorders analyzed by immobilized PH gradient isoelectric focusing using narrow PH gradients.
We analyzed 352 paired CSF and serum samples with isoelectric focusing and immobilized pH gradients (IPG-IEF) using three different gradients. All MS patients (n = 35) had several (from 5 to 30) oligoclonal bands (OBs) in the CSF and most of them had few (from 1-8) OBs in serum. 54.5% patients with CNS infections (n = 12) had oligoclocal bands. OBs in these patients were fewer in number and located at the more acidic pH region compared with the MS samples. Also, corresponding serum bands were more often recognized. We suggest that IPG-IEF improves the diagnostic evaluation of the oligoclonal band pattern. The possibility of the use of extremely narrow gradients makes it a valuable tool for the analysis of selective proteins in various disorders.
