Anti-CALB1 Antibody

Calbindin (CALB1) is a 28 kDa calcium-binding protein of the troponin C superfamily, expressed in cerebellar Purkinje cells, hippocampal interneurons, renal distal convoluted tubules, and pancreatic islet cells. This Antibodies.com rabbit polyclonal reagent is supplied as 100 µl of unconjugated antibody validated for Western blot and immunohistochemistry workflows. On Western blot membranes, the antibody labels a discrete band near 28 kDa in human and mouse tissue lysates. In immunohistochemistry of formalin-fixed paraffin-embedded sections, it acts as a histochemical marker of Purkinje cell bodies and GABAergic neurons, with reactivity confirmed for both human and mouse specimens. The reagent supports neuroscience, renal pathology, and pancreatic islet research; brief centrifugation before aliquoting is recommended, and refrigerated storage preserves long-term activity. Avoid repeated freeze-thaw cycles to maintain titre.
