Background

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).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
