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.

Vitamin D-dependent 28 kDa calcium-binding protein (calbindin D 28k or CB) is a member of the calmodulin superfamily of calcium binding proteins discovered in 1966 by Wasserman and Taylor. The protein has a distinct distribution in the brain and sensory system and is abundant in specific neuronal cell types. Calbindin D-28k constitutes as much as 0.1-1.5 % of the total soluble protein in brain and it may be present at intracellular concentrations up to 1 mM. Several recent studies have shown that calbindin D can protect cells from degeneration and ischemic injury under extracellular stress. In particular, this is demonstrated in the brain of Alzheimer’s disease patients. Cells containing calbindin D have a considerably lower plaque and tangles burden than those lacking this 28 kDa protein.
