LP230270-3   Contactin-associated protein 2
Contactin-associated protein 2 (CASPR2) is present in the axons of the granule neurons of the cerebellum and the juxtaparanodal region of myelinated axons. Increased titers of CASPR2 antibodies were first discovered in patients with Morvan's syndrome. Symptoms of Morvan's syndrome include neuromyotonia, insomnia, autonomic dysfunction and neuropathic pain. Though CASPR2 antibodies have been found in 10% of patients with idiopathic cerebellar ataxia, no specific disease has been attributed to patients with the rare occurrence of positive antibodies for CASPR2 with cerebellar involvement.

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,
