Calretinin (CAL6) Mouse mAb recognizes endogenous levels of Calretinin protein.

Monoclonal antibody is produced by immunizing animals with a prokaryotic recombinant protein corresponding to the entire human Calretinin protein.

Calretinin (29 kDa calbindin, calbindin 2) is a calcium-binding protein of the EF-hand family encoded by the CALB2 gene. It is differentially expressed from homologous family member calbindin-d28k in distinct neuronal populations of the retina, auditory system, and cerebellar granule cells (1,2), and acts as a marker for specific neuronal subsets of the subthalamic nucleus and the substantia nigra (3). Calretinin has been shown to play an important role in modulating neuronal excitability and the induction of long-term potentiation (1). Research has shown that, pathologically, Calretinin is a selective marker for epithelial mesothelioma, making it a diagnostic tool to differentiate from adenocarcinomas (4).
