PCA-2 (Purkinje Cell Antibody 2) Line Assay and Purkinje Line Assay
AVAILABLE ON REQUEST
PCA-2 Line Assay
Line Assay for the detection of paraneoplastic PCA-2 autoantibodies to the Mikrotubulin-associated protein MAP1B
Purkinje Line Assay
Line Assay for the detection of paraneoplastic PCA-2 autoantibodies anti-Yo (PCA-1), anti- MAP1B (PCA-2), anti-Tr (DNER) and anti-Protein Kinase C ɣ (PKCɣ)
PCA-2 autoantibodies are known for almost two decades. These autoantibodies bind to a 280 kDa protein in dendrites and somata of Purkinje cells showing a typical staining pattern.
Clinical symptoms comprise cerebellar ataxia, brainstem, and limbic encephalitis, autonomic or motor neuropathy and Lambert-Eaton myasthenia syndrome (LEMS).
As underlying antigen MAP1B, a member of the microtubule-associated protein family (MAP) has been identified.
Small cell lung cancers (SCLC) are the most common associated tumours.
Autoantibodies to MAP1B often co-exist with autoantibodies to GAD 65, HuD, CV2 (CRMP5), Amphiphysin and SOX1 and also with autoantibodies to surface proteins like VGKC and VGCC (Voltage Gated Potassium resp. Calcium Channels).
