Calretinin, monoclonalCatalog number: CA130
The antibody is suitable for the detection of Calretinin in neurons and may be used as an aid in differential diagnosis of pleura-mesothelioma. This marker is frequently expressed in epitheloid mesothelioma, while occasionally it turns positive in sarcomatous mesothelioma and carcinoma. It was found to be negative in sarcoma (2,3) and in 90% of adenocarcinoma. Calretinin is a Calcium-binding protein related to Calmodulin and Calbindin. It is found in groups of neurons of the brain cortex, in the retina and in the spinal cord (1). More recent studies show that it is a suitable marker for mesothelioma of the lung (2, 3, 4, 5). Calretinin, no cross-reaction with Calbindin and Calmodulin.
Immunogen: Recombinant human Calretinin 22kDa
Antibody solution in stabilizing phosphate buffer pH 7.3. Contains 0.09 % sodium azide**. The volume is sufficient for 200-500 immunohistochemical tests (100 µl working solution / test). Use appropriate antibody diluent e.g. BIOLOGO Art. No. PU002, if further dilution is required.
