General description

Calbindin-D-28K (also termed vitamin D-dependent calcium-binding protein, or cholecalcin), is a highly conserved 28 kDa calcium binding protein, with broad tissue distribution. Itbelongs , to a family of low molecular weight calcium-binding proteins (CaBPs). Calbindin-D-28K is found predominantly in subpopulations of central and peripheral nervous system neurons, and in certain epithelial cells.

Immunogen

synthetic peptide corresponding to the C-terminal region of rat calbindin-D-28K (amino acids 185-199). This sequence is identical in the corresponding human, mouse and bovine calbindin-D-28K sequences and is highly conserved (single amino acid substitution) in chicken and frog calbindin-D-28K.

Application

Anti-Calbindin-D-28K (KD-15) antibody produced in rabbit has been used in:
  • immunocytochemistry
  • western blotting
  • microarray
  • immunohistochemistry

Biochem/physiol Actions

Calbindin 1 (CALB) is a calcium-binding protein. The protein may play a role in development of Purkinje cells found in heterotopias and cerebellar dysgenesias. It also acts as a very important component of intracellular homeostasis in cerebellar neurons. The progressive decrease of calbindin content in the Purkinje cells undergoes degeneration and death during paraneoplastic changes in the cerebellum. Calbindin effects on Parkinson′s disease (PD) risk displays population specificity.
Calbindin-D-28K is an important neuroanatomical marker. Despite its broad tissue distribution, it exhibits a cell-type-specific expression pattern. It has been immunocytochemically localized in selected cells in hippocampus, where it is thought to buffer intracellular calcium, or transport intramembranous calcium.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide.

Analysis Note

Enzymatic predigestion of formalin-fixed, paraffin-embedded sections by proteolytic enzymes (e.g., 0.1% trypsin or protease, 10 min. at RT or 37 °C) improves immunohistochemical staining.

Purkinje cells in the cerebellum express the antigen zebrin II (aldolase C) in many vertebrates. In mammals, zebrin is expressed in a parasagittal fashion, with alternating immunopositive and immunonegative stripes. Whether a similar pattern is expressed in birds is unknown.

Many neurons of the vertebrate central nervous system (CNS) express the Ca(2+) binding protein calbindin D-28k (CB), including important projection neurons like cerebellar Purkinje cells but also neocortical interneurons. CB has moderate cytoplasmic mobility and comprises at least four EF-hands
