Description

Rabbit Polyclonal Antibody

PA1-931 detects calbindin D-28k protein in rat samples. PA1-931 has successfully been used in Western blot , ELISA, immunoprecipitation and immunohistochemical procedures. By Western blot, this antibody detects a 28 kDa protein representing calbindin D from rat cerebellum and rat kidney extract. Immunohistochemical staining on paraffin sections demonstrates that calbindin D is localized to the cytoplasm in epithelial cells of distal tubules in human kidney cortex after staining with PA1-931. The PA1-931 immunizing protein corresponds to the purified 28 kDa calbindin-D protein from rat kidney. Reconstitute in 100 μL PBS to create a stock of 1 mg/mL.

Calbindin-D-28K (also termed vitamin D-dependent calcium-binding protein, or cholecalcin), is a highly conserved 28kDa calcium binding protein, with broad tissue distribution. It belongs, together with calmodulin, S-100, parvalbumin, troponin C and other proteins, to a family of low molecular weight calcium-binding proteins (CaBPs). These CaBPs have homologous primary structures, which contain conserved polypeptide folds of the EF-hand type for Ca2+ binding. Calbindin-D-28K is found predominantly in subpopulations of central and peripheral nervous system neurons, and in certain epithelial nervous system neurons, and in certain epithelial cells involved in Ca2+ transport such as distal tubular cells and cortical collecting tubules of the kidney, and in enteric neuroendocrine cells.
